All About Tires


Tire Pressure The correct pressure to carry in your tires is probably the most misunderstood topic concerning vehicles. Let's start by stating the correct pressure is NOT the max pressure on the sidewall. Anyone that tells you different is full of it.

The correct pressure is determined by weighing each axle and consulting the tire manufacturer for the pressure for that weight. Search for 'suggested tire brand rv tire pressure'

Weighing the RV You need to know the weight on each wheel, each axle, and the all-up weight. The LD should be weighed with the gas and propane tanks full and the freshwater about 1/2 full and the storage tanks empty. All gear normally carried and all humans should be aboard for the weigh-in. You should seek out a segmented scale, rather than a platform scale. Commercial truck stations have such scales.

Knowing the axle weights you then refer to your tire manufacturer's recommended pressure for those weights.

Here's an illustration for Michelin XPS RIB's 


If the front axle weight is 4,200 and the weight is equally distributed left to right (and it should be reasonably close) then each tire is supporting about 2100 pounds so the proper pressure should be 60 pounds. 

If the rear axle weight is 9,600, then each tire is supporting about 2,400 pounds so the proper pressure should be 70 pounds.

(Note if the tires were arbitrarily set to 80 pounds each that would support over 15,000 pounds which exceeds the Ford chassis rating of 14,400. Expect wearing on the center of the tire)

Having the correct tire pressure was brought, almost forcibly, home to me after having Michelin XPS RIB's installed. I set the pressure according to the Michelin specs for my axle weights. Except I confused 55 with 65 in the front tires. This caused the front end to "float". The rig would wiggle around on the road above 50. It was fine without the Jeep, but the force of the Jeep on the rear end actuated the sway. After adding 10 pounds to get the correct pressure of 65 it returned to its normal tracks like a train mode.

I have heard many owners complain about sway. They added rear sway bars. I wonder if the sway bar just masked under inflation? I think I know the answer.


Tire Stems

Consider installing long, specially configured brass valves; these valves make checking tire pressure and airing the tires much easier! (These are NOT tire stem extenders, which many consider dangerous) They are available from several sources. Search for Borg valve stems. Today I see them at
https://www.shinyrv.com/product/dually-valve-stem-kit-for-class-c-ford-e350-e450-dl1ec-free-shipping/




Metal Valve Caps - Spend $5 and get them (Required on commercial trucks) Take them off when you get your tires changed as they will vanish)



ABOUT YOUR TIRES  (UPDATED 2022)


READING A LIGHT TRUCK TIRE SIDEWALL


Rub a piece of chalk over any markings that are difficult to see/read; the chalk makes the letters stand out.  


  • LT = light truck  (Not all “light truck” tires are appropriate for RV use!)  
  • 225/75R/16E is the tire size on the Ford E-450 chassis.  '225' is the tire’s width in millimeters.  '75' is the aspect ratio, i.e., the relationship of the sidewall height to the tire width; the sidewall height is 75% of the tire width.  'R' indicates a radial tire.  '16' is the diameter – inches – of the wheel (rim).
  • Load range relates to the maximum load an individual tire can carry; on LT tires, a letter indicates the load range, e.g., D or E.  
  • The maximum load capacity for the individual tire (stamped on the sidewall of the tire) is indicated as 'X' pounds when the tire is used as a single.
  • The tire’s maximum cold pressure is indicated near the maximum per-tire load ratings.
  • Tire markings vary according to the manufacturer, but the tire’s description/specs should include its intended use, e.g., commercial, highway all-season, etc
  • The number and composition, i.e., polyester or steel, of belts under the tread and plies in the sidewall are (usually) indicated near the tire size marking.  E load range tires should be 10-ply.
  • The date of manufacture of the tire is located in one of the 'DOT boxes', small rectangles containing the tire’s identification, serial number, etc.  Beginning with the year 2000, the manufacturing date is indicated by a four-digit number; the first two digits represent the week of manufacture, and the last two digits show the year of manufacture.  For example, '3519' means that the tire was made during the 35th week of 2019.


TIRE TIPS


     Tire Rack offers the most comprehensive, updated listings of available LT225/75R/16E tires. Search tire listing websites by tire size, not by vehicle.

https://www.tirerack.com

All-steel, i.e., steel mesh belting and sidewall reinforcement can be a good choice, but the selection is (currently) limited to two manufacturers.

Goodyear G947 RSS Armor Max, G949 RSA Armor Max


Tire wear patterns indicate over/underinflation, poor wheel alignment and balance, damaged wheels, and/or suspension problems.   

Over-Inflation Wear

Tire wear in the center of the tread pattern tells you that the inflation patterns are too high. Too much pressure can cause the contact patch to shrink and the center of the tire to carry all of the load.


Under-Inflation Wear

Tire wear on the edges of a tire will typically indicate inflation pressures are lower than specified. When a tire is under-inflated, the contact patch grows and the load is carried by the outside edges of the patch.


Feathering

The indicator of excessive positive or negative toe angle is a feathering or scuffing that can be detected by stroking your fingertips across the edge of each tread bar or tread block. A feather edge on the inside of the tread bar indicates excess toe-in, while a feather edge on the outside of the tread bar indicates toe-out. Because the angle is affected by changes in camber and caster angles, it’s always the last angle to be adjusted during the wheel alignment process. In addition, any change in camber or caster angles will immediately change the toe angle. Toe angle geometry can also be greatly affected by changes in suspension height.

Scalloped

Cupped or scalloped dips appearing around the surface of the tread could indicate loose, worn, or bent suspension parts. Worn shock absorbers or unbalanced tires can also cause cupping, but the cupping would typically be more indicative of a concentric pattern. Shocks and struts are the most likely culprit because they provide damping force to control tire movement. When the tires move excessively, the scalloped pattern can appear. A lack of rotation can cause this condition.


Outer Edge Wear

Wear on the outer edge of a tire is rare these days, but it does happen. Positive camber, caster, and toe can lead to wear on the outer edge. If you see edge wear on one side, check the thrust and setback.

But, it should be noted, that the leading cause of outer edge wear on modern vehicles is over-enthusiastic cornering.


 Inner Edge Wear

Inner edge wear on tires is the most common problem most technicians see. The angles causing this type of wear are typically negative toe and camber. For parts, there are three component sources of the inner edge wear: bushings, springs, and loads.


  •  Bushings

Ozone, extreme temperatures, and other atmospheric issues tend to destroy rubber bushings and cause the alignment angles to change. Some vehicles have hydraulic bushings on the rear lower control arms. Some bushings will leak when they fail. When a bushing in the rear fails, the extra movement causes the wheels to toe out and the camber to go negative.

  •  Springs

As a suspension compresses and rebounds, the alignment angles change. Engineers tune alignment angles for a specific ride height to maximize handling and tire wear. If a spring can no longer support the vehicle, the alignment angles will suffer. Most engineers tune the suspension to toe out when the rear suspension compresses. This increases vehicle stability. But, it also causes the inner edge of the tire to wear. Springs are made of metal that is heat-treated but can still fatigue. This includes leaf, coil, and torsion bar springs. If you see a vehicle that needs considerable adjustments for camber on both wheels of the same axle, inspect the springs.

  • Loads

Loads in the rear of the vehicle will cause changes to the toe, caster, and camber in the front (and possibly the rear). The camber and caster will become positive in the front, and if the vehicle has an independent rear suspension, the camber will become negative and it will be toed out. This could lead to outside edge wear in the front and inside edge wear in the rear.

Chalk Test - You can visually determine if the tires are over or under-inflated with what is known as a chalk test. There are numerous YouTube and explanatory articles that can be found by searching for ‘chalk test’. All you need is a piece of chalk, an empty parking lot, the rig loaded as it would be going down the road and 15 minutes.


Use the recommended tire application, size, and load rating for your RV


    Look for the certification sticker on the door jamb of your LD; it contains information about tire size/type, recommended tire pressures, and tire weight capacities.


Light Truck is the somewhat confusing tire designation used for tires that are the appropriate size and application, i.e., designed for commercial or RV use, for your E-350/450 chassis.


Commercial grade/RV tires are often made of better grades of rubber, contain more UV and ozone protectants, and may have additional plies of polyester (or another material) in the sidewalls, and/or extra belts under the tread; these are usually steel 'mesh'. 


Use the appropriately-sized tire for your wheel.  Using even a slightly wider tire than the 225/75R/16E, i.e., a 2/5” larger 235/75R/16, reduces the amount of space between the duals.  Less space means excess heat build-up and possible blistering (and weakening) of the tires’ sidewalls.  


Also, 'non-spec' space between duals leads to possible contact between the duals when the tires flex during normal use; contact can cause the tires to 'scrub' and weaken the sidewall.  (And, the wider tire may not form a thorough seal when seated on the rim.) Never install a 16.5” (bead width) tire on a 16” rim, or vice versa.


Load rating E is the appropriate choice for the E-450 Ford chassis.  

Currently, Michelin, Goodyear, Bridgestone, Kumho, Toyo, and B.F. Goodrich are among several manufacturers that offer at least one LT/225/75R/16 E-load range tires that are appropriate for use on the E-450 chassis.  Check each manufacturer’s website for tire choices of the appropriate size, load rating, and application; the availability of tire models and applications changes frequently! 


Note:  The 'M+S' tire tread designation means that the tread grooves are wide and begin close to the outside edge of the tire; the wide tread grooves allow mud and snow to be thrown off more easily than from a narrow-grooved highway tire.  Sipes, usually hook-shaped or zig zag slits around the outer edge of the tire tread, provide increased traction on wet roads. M+S tires are not true snow tires; they are classified as all-season tires, suitable for a variety of road applications. 


        The most common causes of tire failures are overloading and underinflation.  


Weigh your coach, loaded and ready for the road, on all four 'axle corners'; the weight (of each corner of) your coach determines the inflation pressure(s) of your tires.  


All tires on the same axle should be inflated to the same pressure; if there is a weight discrepancy between the right and left side of the RV, air the tires to accommodate the higher weight.


Don’t exceed the maximum cold tire pressure, stamped on the tire sidewall (or the GVWR of your coach!)  If your weight indicates a tire pressure over 70 pounds, remove the rocks and scrap steel you are grossly overloaded.

  

     Load Rating Tables

Individual tire manufacturers’ websites offer tire care tips, application, size, load rating information, and inflation tables for their tires; check selections among LT225/75R/16E Examples of load rating tables.


https://www.michelinrvtires.com/reference-materials/load-and-inflation-tables/#/


www.goodyearrvtires.com/tire-inflation-loading.aspx


A closer look at a load range table. Using the Michelin XPS Rib as an example.





If the front axle weight is 4,600 pounds, then the proper inflation would be 65 pounds. (2,300 per tire x 2)

If the rear axle weight is 9,200 pounds, then the proper inflation would be 75 pounds.

(Note 4,600 + 9,200 is 13,800, the typical weight of a 26-foot going down the road with full gas, 2/3 water, and empty storage tanks)

Make sure you are typical and get it weighed.


TIRE MAINTENANCE


Inspect your tires regularly; don’t forget the inside duals!  Check the sidewalls for cracking, checking, bulges, tears or (excessively) scuffed areas.  (Also check the tire bead area for any gouges or shredded or missing rubber.)  Check the tread for tread depth, uneven wear, rocks or other road hazard debris, and any cuts or areas of missing rubber.


Tires deteriorate much more quickly when exposed to UV light and ozone in the air; wash tires with mild soap and water and rinse thoroughly.  Keep tires covered while the RV sits in storage or at a campsite.


Do not use tire dressings or vinyl/rubber treatments containing petroleum distillates, e.g., Armor All, on your tires or any vinyl or rubber surface; using these products can actually increase the rate of deterioration.  303 Aerospace Protectant is the good stuff!   https://www.goldeagle.com/brands/303-products/


RV tires should usually be replaced when the tires are about 5-6 years old, even if the mileage is low and the tread still appears good.  The sidewalls of RV tires are far more vulnerable to the effects of weight and wear than the tread, and time and exposure can deteriorate tires faster than use.


Tire Stores - You should seek one that normally handles larger vehicles. 


Install long brass valves; these valves make checking tire pressure and airing the tires much easier!  Search for dually tire valves or Borg tire valves.




http://yourtireshopsupply.com/category/796/dually-valve-kits is one source for these valves. These are NOT extensions, which can be dangerous.


Carry a reliable, accurate truck/RV tire pressure gauge that registers tire pressures up to about 100 pounds.  The pencil types are less accurate than numbered or digital read-out gauges.  Make sure that the gauge head is deep enough to allow a complete seal around the tire valve when you check the tire pressure.  Do not rely on the gas station or even tire shop gauges that are attached to the air hose; these are notoriously inaccurate.  


Make sure that the gauge selected is for truck/RV use, i.e.; the gauge needs to measure high enough pressures and be of a configuration that allows you to reach the valves to check the air pressure. I use an Accutire MS-4021B Digital Tire Pressure Gauge; see Amazon. Jayco is another quality vendor. A flexible hose is a plus.


Besides the gauge, other handy tire tools are a valve core tool, extra valve caps, an old (dull) screwdriver to pick rocks out of the tread, and a depth gauge measure.


Check your tires’ air pressure before each day’s driving; the tires have to be cold for an accurate reading.  'Eyeballing' does not substitute for using the gauge to verify correct tire pressures!


A laser digital thermometer is useful to quickly check tire pressure/temperature at a rest stop. You just walk around the rig and shoot all six tires noting the temperature. You will quickly learn what a normal temp is. The inside dual will always read a little higher than the outside.  80 to 120 degrees depending on ambient temp are normal.




Use metal valve caps to keep dirt, debris, and moisture out of the tire valves; these can damage the valve core and cause a slow leak.  The best 'air-through' valve caps are German-made V2B Alligators:

https://www.amazon.com/Alligator-V2B-Inflate-Through-Valve/dp/B014VCY3S2


Depending on speed, ambient temperature, and length of driving time, a tire can inflate to several pounds over its cold inflation (even exceeding the maximum) pressure.  This is normal; never bleed air from a hot tire.


Carrying a small 120V (or capable 12V) air compressor makes airing the tires much easier! 

400P-RV AutomaticPortable Compressor is an example.

https://www.viaircorp.com/portables/400p-rv-auto


If you use wooden or plastic blocks for leveling your coach, make sure that the blocks are wide enough and long enough to support the entire footprint of the tire!


https://trilynx.com/


Always block both rear duals when leveling the coach; never block just the outside dual.  


Air the spare to the maximum pressure listed on the sidewall.

A Primer For The New RV’er

Editor's note, this is a primer of information about RVing. The rest of The Companion contains more detailed information.

Getting Started 
A Primer For The New RV’er

    All of us living the RV lifestyle were new to this once.  We made mistakes.  We wondered where to find stuff.  We worried about what we should be worried about.

    Hopefully, this will be of some help.  It is organized in several general categories - making decisions about buying an RV, driving and maneuvering your RV, campground or campsite stuff, at home or in storage, and a few last odds and ends.

    The intent of this article is not to give you detailed information but rather, to introduce you to a number of topics, thus helping you enter this lifestyle with a bit more comfort.  I will try to avoid things that are specific to certain makes, models or years.  Instead, I hope to give you subjects to think about, give you resources you can turn to, and suggest some approaches to things we all do.  Also, the information here is not irrefutable.  There are differences in RV’s, particularly older ones so that what we talk about here may not apply to your unit.  There are certainly a number of other descriptions for types of camping, and the definitions I provide may differ from what others use.

    Finally, I had help on this article from a number of folks.  Thank you, all.

Topics in this article:
Buying Your RV
In The Driver’s Seat
Campground Stuff
At Home Or In Storage
Odds and Ends

Buying Your RV

    This seems like a good place to start.  You are thinking about getting an RV, but - what kind?  There are motorhomes, Class A, B, and C.  These letters refer to the design of the RV, not the quality.  Class A RV’s look like buses.  Class B RV’s look like a van on steroids.  Class C RV’s have a truck cab in the front, have a boxy area above the cab, and have a box shape behind the cab.  There are Fifth Wheel trailers, characterized by a high front extension that connects in the bed of a pickup truck.  There are Travel Trailers that hook up to a trailer hitch.  These vary greatly in size, ranging all the way down to tiny teardrop campers.  There are Pop-Up trailers that unfold into a camper with canvas sides.  There are Slide-In campers that fit into the bed of a pickup truck.

    While some of what follows is applicable for any and all RV’s, the primary focus of this article will be on Class C motorhomes.

    It can be pretty confusing, so here is the first tip - Find a reliable and experienced RV mentor and keep their phone number close.  That person can help with some of your early questions.  I was very lucky in that regard.  My mentor knew and knows more about electrical systems in RV’s, and little ways to live the life well, than anyone else I know.  As a new person to RV’ing, how can you tell if they are reliable?  Beats the heck outta me, but try.  The second tip - when you have found a possible RV selection, check it out using the Consumers Guide to RV’ing, RV.org.  That site will allow you to compare RV’s by varying manufacturers.  Third tip - you would not buy a house without having a competent home inspector go over your prospective purchase.  An RV is a much more complex item than a home.  Have your prospective purchase checked out by a competent set of people.  You will need a good mechanic to evaluate the engine, transmission, brakes, steering and suspension of a motorhome.  You will need an RV inspector to evaluate the body and the appliances of your RV.  With their help, you will be much more likely to make a good purchase.

    When making a selection, you need to determine if the RV will have enough capacity for your needs.  The biggest issue is weight.  Your cargo carrying capacity (CCC) is how much weight in terms of people, water, waste, gas, books, pets, food, games, clothing, in other words, everything that is not a physical part of the RV, can be carried.  That number can be surprisingly small in some RVs.  A second number you will need to check before buying is the gross combination weight ratio or GCWR.  That is the total weight of everything - the RV, people, fluids, cargo, tow hitch, and any car or trailer being towed.  Do not exceed those numbers.  (This next point is for after you buy, but as long as we are talking about weight, once you own your RV, load it up with everything as if you are starting a trip and take it to a truck scale that can tell you your axle weights.  Your owner’s manual will tell you the maximum load per axle.  Ideally, you will be able to find a place that can weigh all four wheel positions, so you can also see if you are balanced side to side.)

    If you buy new from the factory, they will give you a quick orientation, but there is something that they skip, and that you should know. Ask to be shown the location of the hidden 50-amp fuse. If you lose your 12V power, this is something to check, but you will be tearing your hair out trying to find it on your own.  And these days, I have very little hair to spare…

In The Driver’s Seat

    Bunches of little things here, and a few more significant things…
  • When you pull out and drive for an hour or so, then realize that you forgot to bring something, that can be frustrating.  A checklist of must-have stuff can be useful.  So what should you carry with you?  This depends on your skills and physical abilities, on where you camp and how you use your rig, and varies greatly.  My rig is crammed full of tools and some spare parts.  Over the years there has been a lot of discussion about this in the Forum.  It is worth searching for and reading what people carry to help you make your own decisions.
  • You are no longer driving a car.  Your RV is slower to accelerate, takes longer to stop, and is sluggish on turns.  You may have heard people advise using the 2-second rule when driving a car?  (Maintain at least 2 seconds of travel time between you and the vehicle in front of you.)  Well, in an RV, think more in terms of 3 or 4 seconds.
  • Before backing into a site, either you or, if you have one, your co-pilot should walk it, looking for obstructions or anything that needs to be avoided.  A good way to remember this is the mnemonic GOAL: Get Out And Look.  If you are backing in at night, get out and set cones or other markers for use as guides, making sure to use something you can readily identify in the back-up camera if you have one, or your mirrors. The camera has an array of infrared LED illuminators that are very useful for night use. The factory back-up lights have been enhanced too, making the mirrors useful at night.
  • Unless you can see a way out, be careful about driving into someplace.  You may have to back out.
  • If you are towing a car, you cannot back up without damaging the car’s steering system and the tow bar.  If you HAVE to back up, disconnect the car, back up, then re-connect the car.
  • Bear in mind that most of today’s cars cannot be towed with the wheels on the ground, and you probably cannot accommodate the added weight of a trailer or a dolly, on which you are carrying the car.  Read the car owner’s manual carefully.  When I was getting started I was looking for a car I could tow.  A Hyundai was advertised as being flat towable (four wheels on the ground).  When I read the manual, it confirmed that.  The car could be towed with all four wheels on the ground, for a distance not exceeding 15 miles, and not above 15 mph.  So, beware.
  • Even if someone is directing you, YOU are responsible for your rig.  I do NOT trust campground staff to direct me.  When I was 6 months into the RV lifestyle, a staff person told me to follow him. He jumped into a golf cart and took off.  When he pulled waaaay to the right, so did I.  I stopped when I hit the 10” thick overhanging branch, putting a hole in the fiberglass front cap of my 6-month-old rig. It was MY fault, not his.  I was the driver.
  • If you have a co-pilot, discuss and agree on hand signals.  Two-way hand radios or cell phones can be an effective way to communicate if instructions are clear, concise and precise.  For example, “a little more” is not as useful as “one more foot”.  Remember, if a copilot is helping you park, don’t move your vehicle unless you can clearly see where they are, and that they are out of your way. You don’t want to run them over.  That could ruin your whole day!
  • Watch that rear overhang!  When you turn one way, it swings the other way.
  • When parking, if you are on any grade, put the rig in neutral with the brake on, set the parking brake, then put the rig in park.  If you put the rig in park without the brake being set, it can roll a little, putting a load on the transmission, making it hard to shift out of Park when you next startup.
  • Read the Tow/Haul information in your Ford or Chevy owner’s manual.  With the weight of your RV, it is equivalent to always towing and hauling something.  The Tow/Haul switch, if available, adjusts transmission shift points, as well as helping on downgrades.  Getting the Tow/Haul to downshift may not be clear.  I apply the brakes, slowing to a speed near my target speed.  I then release the brakes and re-apply them, slowing until the transmission downshifts.
  • Now for a biggie - mountain grades.  You have an automatic transmission, but you have more spots on your gearshift beyond just Drive, Reverse, and Park.  These can help with steeper grades. In brief, borrowing from Andy Baird, “avoid steep roads if you can (consult Mountain Directories); check the weather; downshift at the top of the hill, before descending; brake on the straightaway, not on curves; and stop and cool off”.  Don’t worry if traffic behind you is backing up.  Climbing a hill, pushing the engine too hard is not a good thing.  As to downhill runs, if you have tow/haul, and are using it, your manual will tell you that pressing and releasing the brake will downshift the transmission to help control your speed.  It will.  But, if the grade is too steep or too long, it may shift to a higher gear to avoid RPM’s that are becoming too high.  I personally prefer to manually control the gear on serious grades.  On a long but moderate grade, I will shift down one notch.  If I find I have to apply the brakes quite frequently to keep the speed and RPM’s down, I will brake to a lower speed, then shift down another gear.  This continues until I am in the lowest gear.  If I STILL am using the brakes a lot, I will look for a turnout where I can stop and let everything cool down a bit before continuing.  The best thing I can suggest is to be thinking ahead, anticipating what is coming, and make any changes in advance of when they are needed.
    Why is this a big deal?  Your brakes depend on a non-compressible fluid pushing the brakes on.  If the brakes get too hot from too long or too frequent use, that fluid can boil, at which point the contents of the brake line become compressible, and you will no longer have any brakes.  So, think ahead, plan ahead, don’t let anyone rush you, take your time and get down safely.

    Here is a really good link on the subject:
  • TPMS - You will see lots of discussion about this.  It stands for Tire Pressure Monitoring System.  As the driver, you are responsible for your vehicle.  If you do not have a TPMS but you check your tire pressure before embarking, you will know precisely what your tire pressure USED TO BE.  You do not know what it is now.  If you tow a car, and it has a tire go flat, you will not feel it.  I know someone who left a campground and drove 30 miles towing his little sports car with high-end tires and wheels.  His tires were okay when he left.  Thirty miles later, when he pulled into his destination, the right front tire on the car he was towing was gone.  Completely gone.  The wheel was chewed up and the rotor was damaged.  It cost him $1600 to get back on the road.  More recently, I know someone who got a set of new tires and started out.  The next day, his TPMS gave him a low-pressure alarm.  He had 25 psi in his front right tire, and that meant he was close to destroying his new tire.  His TPMS warned him and he was able to deal with it.  So, get a TPMS.
  •  A final small driving tip - load your RV so you are balanced side to side.  An unbalanced rig will not handle as nicely as a balanced one.

Campground Stuff

    First, let’s define a few terms.  Full hookup camping means you have sewer, water, and electric connections.  In sites with partial hookups, it is usually designated as a site with electric.  That electric hookup can be 30 amp, which is what my rig uses or, in some cases, it may be 50 amp.  Electric sites usually (in my experience) include water.  Dry camping is camping in an established site but with no hookups of any kind.  Dispersed camping is camping in an area designated for camping use but without established sites.  Boondocking is camping at a spot where camping is permitted but there has been no particular construction to create a place to camp, e.g. no picnic bench, fire ring, or anything else often found in camping locations.  Such sites are usually tucked away.  (Again, these definitions are not universal.)

    Finally, there is Walmart camping.  Walmart’s corporate policy is to permit RV’s to stay for one night in their lot, usually at the more remote area.  However, some jurisdictions regulate overnight parking, prohibiting this. Before settling in for the night at a Walmart, ask inside if it is allowed. [and many other big box stores like Lowe's. Get creative, we once parked at small-town courthouse, darn safe as it was also the Sheriff's office - open all night] 

Waste management
    When camping with full hookups, your sewer hose should normally have a fitting on the end to seal the opening into the sewer.  If you do not have such, you can still use the site and can dump, but you will keep the sewer closed when not actually dumping, and you must exercise considerable care to not spill when you do dump.  If you do not have a sewer hookup at your site, you will need to use dump stations.

    The manual recommends not dumping the black tank until either your trip is over OR you are at least 2/3 full, so there will be enough velocity formed by dumping to wash the solids out with the liquids.  When you can, clean the tanks. Larry Wade has posted some excellent info on cleaning out your tanks.  It is worth tracking that down and reading it.

    Most Class C RV’s have two separate waste tanks.  One holds water from your sink and shower drains and is known as the grey tank.  The other holds waste from the toilet and is known as the black tank.  Some waste plumbing systems have two separate gate valves and sewer hose connections, one for each tank.  First, make sure you know which valve is which if you have two separate dump valves as I do.  Some units use a single connection with two gate valves.  The black tank valve will almost always be a 3” valve, while the grey tank valve may be either 3” or 1.5”.

    1) Start with the black tank.  Be sure the valve is closed unless you want to look like Robin Williams in the movie, “RV”.  Closed means that the handle, or BOTH handles if you have a single connection, is pushed right up against the black plastic valve body.

    2) With the handle closed, twist off the valve cap and attach the dump hose.  The dump or sewer hose is a corrugated, flexible 3” hose.  It is normally stored in some exterior-accessed space.  Mine is behind a small access door.  I have seen them stored in a 4” x 4” rear bumper, and coiled up in side compartments.  Make sure you HAVE a sewer hose before you hit the road.

    3) With the dump hose attached, place the end into the opening at the dump station. 

    4) It may be wise to use a rock or two to hold the hose in place.  If it kicks out of the hole when you open the valve, things get very messy very fast.  I am used to doing this, so I often just place a foot on the hose to keep it in place.  So far, that has worked.  May it ever be so…

    5) Grab the handle and pull to slide open the dump valve.  BE READY TO SLAM IT CLOSED IF THERE IS A PROBLEM!  Let the tank drain as much as it will.  If you have a hose to rinse the black tank this is the time to do that.  Alternatively, give it a few good toilet flushes. When done, close the black tank valve.  If material remains in the hose, elevate the hose, starting at the rig and working your way to the opening, so the hose has drained fully before disconnecting it.

    6) If you are using a single outlet with two gate valves, it is time to open the grey tank valve.  It will flush residue out of the Y-connection and will flush out your hose.

    7) If you have two separate dump valves, remove the grey tank cap, make sure the black tank valve is closed, remove the sewer hose from the black tank valve and connect it to the grey tank valve.  Open the grey tank gate valve.  The grey tank water will flush out the hose.

    8) When the tank is empty, close the valve and remove the hose.  If there is a rinse hose available, rinse the surfaces of both valves and replace the caps, then rinse the sewer hose, inside and out.  I then hold up the hose by the fitting and compress the corrugations for a few feet to push out any residue residing in the corrugations.  I shift my hold down and repeat until I have cleared the entire hose.  I then put it away, do a visual check that both valves are closed and both caps in place, wash my hands, and off I go.

    NOTE - it is recommended in the manual to add a few gallons of water to the black tank at this time.  If you are actively using the system, I have not found this to be necessary, but if I am going to be driving I will do so to help rinse sludge off the lower tank walls and bottom.  If you are putting the rig away after a trip, this is essential.  Allowing sludge remaining in the tank to dry is a REALLY bad idea.  I heard of a person who had a rig where both black and grey tanks merged at a single outlet.  The person had a campsite with full hookups.  They hooked up their sewer or dump hose, opened both valves, and proceeded to use the system until ready to leave.  They then left, thinking both tanks were empty.  The grey tank was.  The black tank was not.  Liquids had run out but solids had formed a mountain.  They needed professional help to get the tank cleaned out.

Electricity Management
    You have two electrical systems - 12V DC and 120V AC.  Let’s deal with 120V AC first.

    Your 120V AC can come from a cable connected to an electrical pedestal at your campsite, commonly called shore power, or from your generator.  In some cases, an inverter can provide 120V AC using a 12V DC input, but I think that is beyond the basics, so let’s stay with the main stuff.

    Your cable connecting to the pedestal may be permanently connected to your RV, as in older models, or maybe something that you need to connect.  To make that connection, the outlet end of the cable pushes onto the plug in the wall of the RV, then must be twisted clockwise until tight.  The black plastic ring then should be aligned so it can slide onto the connection until seated, at which time it locks by twisting to the right, just like the outlet.  Take the other end of the cable and go to the pedestal.  Make sure the circuit breaker in the pedestal is switched OFF, then push the plug into the pedestal outlet.  Then, switch the breaker ON.  Plugging in with the breaker on has the potential to damage some of your electrical stuff.

    Pedestals are not always wired properly and are subject to voltage irregularities and surges.  A polarity checker will check for improper wiring but does nothing else.  A surge suppressor can handle some “dirty” power but can let some leak through.  An “EMS”—Energy Management System is a better choice, but it costs more.

    An EMS detects not only miswiring at the pedestal and protects against voltage spikes, but it detects poor quality current and low/high voltages and clamps the power to the rig (at pre-set levels) to protect against damage to the rig's wiring and appliances. The EMS re-sets itself and resumes providing power to the rig when the supply is within specs again. Since low (and high) voltages are significant issues that can damage wiring and appliances and are far more common than voltage spikes/surges, an EMS, although more expensive, offers a much wider range of protections. About 9 1/2 years ago, I was at a campground that got hit with a power surge due to a motor vehicle accident.  My EMS got fried, but my “stuff” was fine.  About half the rigs in the campground lost all their electronics.

    So, at minimum, get a polarity checker.  If you can afford is a surge protector, then get that.  But if you really want to protect your equipment, get an EMS.  Here is a link for one manufacturer to various devices and what they do:

    If you see lightning or hear thunder, it is a good idea to unplug the cable from the pedestal.  Turn the breaker off, then pull the plug.  Lightning can travel a LONG way through a power line before it tries to slam into your RV’s system.  Don’t let it in.

    Your generator will deliver 120V AC to your system.  Both the generator and the shore power feed into your system through an Automatic Transfer Switch or ATS.  If you are not getting power into your rig, you may have a popped breaker on the pedestal or the generator, or you might have a bad ATS.  There is considerable stuff published, including here in the Companion, about the ATS.

    Your air conditioner and microwave run only on 120V AC.  Your refrigerator uses either 120V AC or propane.  Either way, it also uses 12V for the control systems.

    Your 12V DC system operates your radio, your lights, your furnace (with propane), your refrigerator (with propane), and water heater (with propane), your fans and in many cases, your TV.  The power comes from batteries.  If your batteries are conventional, deep cycle or marine batteries, they will vent hydrogen, so they can only be stored and used outside.  If you are keeping batteries inside, they MUST be sealed AGM batteries or the much more expensive Lithium Ion batteries.  The batteries will be charged from a variety of sources including 120v AC from the generator or shore power, going through a converter into the batteries, or from the engine alternator or a solar charger.  Keep your batteries between 100% and 70%.  Regularly discharging them below 70% will shorten battery life.  To that end, if you do not have a battery monitor that shows % you may want to add a battery monitor to you list of future purchases.

Water Management
    Your water can come from your fresh water tank and pump, or from a hose connected to a campsite water supply, commonly called a hydrant, or a hose bib.  What you do to manage water depends in part on which source you are using as well as how you use your rig.  If you are out weekends occasionally, with an extended trip once or twice a year, you probably should drain the fresh water tank between use, and sanitize the tank periodically.  If you use it every weekend, this may become less important.  As a full-timer, I have not drained or sanitized my tank in ten years.  This is because, in part, even if I have a water supply at a campsite, I do not hook up to the water supply for daily use.  I use my pump so that the water in my tank is regularly being used and replaced.  It is not sitting unused, so microorganisms have little time to develop.

    When you drain your tank to put it in storage, the fresh water tank is drained by a ball valve near and below the fresh water tank, probably tucked in the corner of a storage compartment.  The drain valve should be closed when done, lest insects and small critters crawl into your tank.

    There are mixed opinions regarding the use of a filter when filling your water tank.  Many use filters, typically when in a campsite that has a water hydrant.  The filter will slow the flow rate significantly, making filling the tank a slow process.  Conventional filters will do a good job of removing any sediment or particulate materials, and some can remove some dissolved materials such as chlorine.  They will not remove microorganisms or heavy metals, nor can they make hard water soft.  To remove microorganisms, you need a filter with a pore size of 0.2 microns or smaller.  The flow rate will be VERY slow.  I do not use a filter and have never had a problem, but that might change with my next fill.  (I choose not to use a filter because I usually do not have a hydrant at my site and using a filter really slows the fill time.) I have heard of others not using a filter who have had sediment come into their tank.

    When filling the fresh water tank, there is either a little screen or a small hole near the fill opening.  It is there to vent the tank and, as the tank nears full, it will spit and sputter.  Keep it clean and clear.

    If you DO connect the RV to city water, be sure you are using a pressure reducing connection.  City water pressure in campgrounds can be high enough to damage your plumbing.

    Many of us turn our water pump off when going away from the rig or when sleeping.  A leak in the system could lead to that pump emptying your fresh water tank into the interior of your rig.  Along those lines a few battery powered leak detectors are a good thing to have.  I have three - one under the pump, one under the bathroom sink and one behind the toilet.

    Your hot water comes from a water heater that runs on propane and 12V DC.  You might choose to leave the heater on all the time but many of us do not.  We turn it on in the morning, then turn it off in 20 to 30 minutes.  We will have warm water all day unless several people are taking showers.

    Your water heater does need some care.  It needs to have a compressible air space called an air bubble, and it needs to be periodically flushed to remove deposits of calcium and lime in the tank.  Instructions for both are available in the Lazy Daze manual, in the water heater manual, and in the Companion.  If you do not have a sufficient air bubble, it makes your pump’s task harder and pressure in the lines can rise to the point that your system develops leaks.

    The air in the air bubble becomes absorbed by the water. This absorption can happen in a month or so, so re-establish the bubble as needed. Some clues that the air bubble needs to be restored include a pump that turns on as soon as you open a faucet and turns off as soon as you close it and water flow that seems to increase and decrease with the pump cycling on and off.  There should be some lag in the pump response time, and the water flow should be relatively steady.

    If you are re-establishing your air bubble, a few points deserve emphasis.  First, do not do it unless the water has cooled, lest you burn your hand.  Second, make sure you have opened a faucet so as water flows out of the tank, air can come in to replace it.  Third, when done, let the handle of the pressure relief valve snap down hard so it seats itself properly.  Don’t lower it; snap it down.  Finally, wipe the heater surfaces dry, then close the faucet and turn the pump back on.  A day later, look for any sign of dripping or leaking at the pressure relief valve.  If there is any sign of dripping, open and snap closed the valve again.  Repeat, until there is no sign of a drip.

    Your water heater will need to be flushed occasionally.  The frequency depends on your usage and your water supply.  I do it 3 times a year.  Dissolved lime and calcium sediment will condense and accumulate in the bottom of your water heater.  To protect the heater and preserve its efficiency, you need to flush that stuff out.  Look for a how-to video online.  Short form, you remove the drain plug from the water heater when the water is cool.  Let it drain.  Connect a flush tool to a hose and work it in and out of the tank, spraying the jet back and forth over the bottom of the heater, washing the sediment out.  It takes me about 20 minutes of flushing before I no longer see flecks of white stuff coming out.

    You may experience sluggish flow in your faucets at times.  This often happens to me after I have flushed the water heater.  The most common cause is particulate matter, formed in the water heater tank and stirred up by flushing, gathering on the strainers or at one of the points of constriction in the system.  Tracking down just where the constriction is located can be a pain, but is not something that requires urgent attention.  Enjoy your campground stay and deal with the low flow later, as long as you have enough flow to manage until then.

Campground Manners
    Quiet at night, and minimal light that might infringe on your neighbors at night…

Leveling
    It matters.  Your refrigerator can be damaged or destroyed if you are sufficiently off level for a long enough time.  Some use blocks under the tires to level.  Some use mechanical devices such as hydraulic systems.  Some hunt until they find a very level campsite.  Whichever you choose, if your refrigerator is on, and you are not driving, you should be level.  How level is “level”?  It doesn’t have to be perfect.  In the Lazy Daze manual it says that you should be level enough to walk around comfortably.  That will vary too much for me.  I use an 8” torpedo level and I want to be no more than a half bubble out of level.

Watching TV
    Most of us have a TV antenna on the roof called a batwing antenna.  The antenna is raised and lowered by a crank on the ceiling.  Its alignment can be changed when raised by pulling down the disk with a pointer behind the crank and rotating that disk.  Before trying to lower the antenna make sure the pointer is back in its original position, else you could damage the mechanism.

    The antenna has a pre-amplifier built into its head.  The signal comes down to a plate on the wall where a coax cable connects between the plate and the TV.  Next to that coax cable is a tiny little button.  That is for an amplifier.  It draws power from a nearby rocker switch.  Here’s the thing - if the amplifier is not on, you will not get a signal from the antenna for the TV.  If the amplifier IS on and you have connected to a cable TV hookup in the campground, you will not get the cable signal.  To get cable, the amplifier must be off.

    To optimize your broadcast TV viewing, you need to aim the antenna.  I do it by raising the antenna, then I do a scan with the TV to see HOW MANY stations I get.  I then turn the antenna 60 degrees by pulling the alignment plate down to unlock it and turn it left or right, and scan again, noting the number of channels I get.  A third time, again 60 degrees, and check.  I then return to the one that gave me the most channels, then rotate 180 degrees for another scan.

    I now know the approximate direction I want to use.  By tweaking the alignment about 20 degrees left and right I can see if the channels I am watching get snowy or stay clear.  When I have tweaked the alignment as best I can that way, I do a final scan and settle down to watch TV.

    Why 60 degrees?  Why not 90?  I used to do 90, but realized I was doing more scans before I could identify the best alignment.  I found 60 to be easier and more efficient.

    Note that the alignment with the most channels may not be the best for you.  At Caballo Lake State Park in NM, the commercial stations all come from an antenna 15 miles due north of the campground, but PBS comes from an antenna 30 degrees to the right and 4 or 5 miles away.

    It is very easy to forget that the antenna is up and to drive off that way.  I use a colorful piece of rope or a ribbon tied to the crank handle when the antenna is up, making it less likely that I will forget to lower it.  Remember that it must be aligned to lower it.  It can’t be turned at an angle, else trying to lower it could damage the mechanism.

    Getting satellite TV is possible in an RV.  How that is done varies greatly.  There is an article in the Companion about how to do it.

Toilet Stuff
    The toilet should have water standing in the bowl between uses.  The standing water is what blocks fumes from the waste tank from coming up into the RV interior.  When done, flush by pressing down the flush pedal and keeping it down until the bowl is clear of waste.  You can hasten that by using the hand spray attached to the toilet.  Don’t close the flush mechanism until the bowl is clear, lest you push waste into the seal area.  When the bowl is clean, release the pedal and let it snap up.  It is not meant or intended to be released slowly and gently.  Doing so may allow it to leak.

    If the toilet does not hold water in between uses, get some white vinegar and pour it into the bowl and let it soak a bit, then brush the edges of the seals.  Rinse.  Repeat if needed.  If water still leaks out of the bowl, most likely the upper pair of seals need to be replaced.  There are detailed instructions for doing this elsewhere in The Companion, and there are videos online about how to do it.  It is a fairly straightforward task that is not hard to do, but demands some care and attention to detail to do well.

Propane Stuff
    If you use your refrigerator other than when plugged in, or use your water heater, your furnace, your stove or oven, you are using your propane.  Here are some things to know.  First, in the tight spaces in an RV, it can be easy to “butt dial” one of the knobs on the stove, turning it on slightly.  If you smell gas, look there first.  If the knobs are all off and you are smelling gas, get out of the rig.  Open the access door to the propane tank and turn off the valve that controls propane flow.  Don’t turn it on again until you have found the source of the leak.  And don’t look for the leak with matches…  We’d like to keep you around for a while.

    When you get your propane or your gas tank filled all ignition sources must be off.  That means the furnace must be switched to the OFF position.  The refrigerator must be switched OFF at its panel, not unplugged in the outside compartment.  Unplugging it just assures that it is running on propane, not electricity. The important reason for switching it off at the fridge’s control panel is to prevent it from trying to spark and ignite.  Your water heater must be switched OFF.  These do not have to be done a block away from the gas pumps.  Pull in, get up and switch everything off, then pump your gas.

    For a propane fill, I turn my propane supply valve off rather than letting the propane fill person do it.  I do so because that valve has a small needle valve with a brass seat.  Some propane guys have grips like gorillas.  If I turn it off, I will turn until it is snug, but I am not leaning on it.  Tightening it too much can damage that seat, which would require replacement.  When I turn it on, it is the same.  I open it until it is snug but I don’t crank down on that knob.  If you do not know which knob turns off the propane valve, ask the propane fill person to show you, the first time you fill up.  When filling with propane, all persons and pets should be outside the vehicle.

    When the gas or propane tank is full, as long as there is no heavy odor of gas or propane near the rig, you can turn stuff on and drive away.  Immediately after a propane fill, there WILL be vapors but, if you go inside and pay for the propane, by the time you come back out it will be safe to open the valve, go inside, and turn the water heater and refrigerator on again.
    One last note about propane - in storage, turn the valve off.

Cold Weather
    Camping in cold weather brings out more issues.  The cab is a huge source of heat loss.  Find a way to insulate the cab from the rest of the rig.  A lot has been written about that in the Forum and in the Companion.  Your mentor is likely to have good information on that.

    If you are in weather below freezing, and you are keeping the interior in the ’60s or warmer, the only thing you need to do about your fresh water supply is to open cabinet doors and access panels to areas like the water pump.  Run your water heater for 20 minutes before going to bed.  Your fresh water supply won’t freeze.

    Your grey and black tanks, however, CAN freeze, but that is probably okay, right up until they are full and you need to dump.  If you are camping in sub-freezing temperatures, plan to be out of there and someplace warm enough to thaw those waste tanks before they are completely full.  I once froze my grey tank completely, and I was in Florida for a week before I stopped hearing ice banging around in the tank.  Plan accordingly

    Lastly, your furnace will use propane far quicker than any other appliance.  Keep an eye on the propane level so you do not run out.

Getting Mail and Packages
    If you are out for a weekend or a week, this is not an issue but longer trips may call for a variety of strategies.  You can receive mail at any post office near you.  Have it sent to you, General Delivery, at that Post Office.  That works for up to 2 weeks at any post office.  If you will be in one area for substantially longer, you can rent a PO Box.  I rent one in the northwest in the summer and in New Mexico in the winter.  As a full-timer, I use a mail forwarding service.  All my mail goes there, all year round.  If I am traveling, they will send it to me, General Delivery, to a post office ahead of me on my route.  If I have a PO Box somewhere, they send it there, once a week.  Your instructions may well be different, but that has worked well for me.

    Packages are different.  The Post Office usually cannot accept a package from Fedex, UPS, DHL or others unless some postage has been paid to the post office to do so.  The post office calls this service “the last mile” delivery.  Shipping charges include postage fees and provide for the commercial carrier transporting the package to the post office, and the post office accepts the package and delivers it to you.  In general, if you are in a commercial campground, they can accept Fedex and UPS packages.  That may not be the case in public campgrounds such as BLM, Forest Service and Park campgrounds.  You may be able to find a local service such as The UPS Store or similar where you can have a package delivered for a fee, or if there is a UPS Customer Service Center, they can accept and hold a package for you marked “Hold For Pickup”.

Departing
    Okay, we covered the campground stuff.  Now it is time to leave.  I suggested having a checklist for starting out so you don’t forget stuff to bring.  Well, many of us have a checklist of things to verify before pulling out.  It is likely to include checking that the antenna is down, that all cabinets are closed, that all items that can shift are secured, and so on.  After completing the checklist items, do a walk-around the rig.  Look low to make sure the waste valve caps are on, all wires and hoses disconnected and stowed, and the steps stowed.  Look high to make sure the awning is fully seated and the antenna is down.  Check all lights.  Make sure hydraulic levelers are retracted.  Pull forward and retrieve any leveling blocks and stow them.  Taking a minute to do a careful check of everything outside can really save the day.  If you are towing a car, after hooking up, do a careful visual check and a physical (pull and tug) check.   

At Home Or In Storage

    Turn the propane off.  Turn off the refrigerator and empty it, leaving the doors open.  Put a good amount of fresh water in the toilet so the seals stay wet, then dump the fresh water tank.  Thoroughly clean and dump the waste tanks.  Read what Larry Wade had to say on this.

    If you are facing cold weather, winterize your RV.  There are several ways to do this but they revolve around either blowing out the lines and draining the water heater or using RV antifreeze solution or both.

Odds and Ends

Solar Power
    Some rigs have a lot, some have a little and some have none.  If you plan to camp under the trees, solar panels will do little for you.  You need open sky above you.  Avoid shadows from tree limbs, structures and utility lines.  In the winter in northern regions, you will get very little benefit from solar panels unless you have a lot of them.  Of course, if you plan to be plugged into shore power, you won’t need solar panels.

    A good solar setup can allow you to be an electricity hog like me without the need to run your generator.  To get maximum benefit, I pick sites with open skies, and I hope for clear weather.

    Nobody can tell you how many panels you need without having an understanding of where, when and how you will use your RV, what your electrical needs are, and what you want your system to do.  For many, one panel is enough.  I have five, and I could use six.  If you have solar, or you are thinking of expanding an existing system, the smartest thing you can do is to work with a pro who knows what questions to ask, and knows what will work for you.

Useful Resources
    First and foremost, the manuals for your equipment are the most authoritative source of information.  Use them.  In fact, the Manual should be the first resource to which you turn.  Your secondary source probably would be knowledgeable people.  That would include your mentor, people in the Forum that seem to have a good handle on the subject, and professional service people.  Third would be The Companion.  Fourth would be discussions, sometimes heated, in the Forum.  If you need but don’t have a Manual for one of your appliances, the chances are good that you can find one at http://www.manualslib.com

    When registering or reserving a site, if you are towing a car, that usually does not count as a second car with a separate fee.  If the second car is driven in, then you may have to pay more for it.

    You may want to have a roadside assistance plan.  This is basically someone you can call for help when you are stuck on the side of the road.  I have CoachNet.  I have called them once in 10 years, but when I called, I really needed help and they got me that help.
