Does everyone need to winterize their Rigs In The Fall?
Should We Winterize Our Class C Motorhome... When Do We Really Know If This Is Necessary?:
Well, I guess that depends. Some of us have limited options on this matter, and some of us just have to prioritize our calendar... and I'm sure there are a bunch of people in between these extremes. Besides, what does it mean to to get an RV ready for winter anyway?
Does this word describe packing-up and moving to a warmer environment? Or does it require some type of preparation against cold weather?
Maybe you will have issues with critters wanting to make a home out of your Class C when it gets cold. Are there things you can do to prevent this?
Maybe you just want to be able to use your Class C Motorhome in a cold climate.
If you are knee deep in snow and like it that way... that means you may be a skier of some type... down hill or cross country. You may have already purchased your rig with heated tanks and triple paned windows. If not, you can perform some aftermarket additions like energy saving window film to help keep the cold in check.
Right at the top of the list, you may want to investigate a
more efficient propane heater.
You can also add extra insulation to the rig whether it is a spray-on that would go under the chassis area, or simple inserts that protect the roof vents.
Bottom line, there are options out there that enable comfortable cold weather activities. If your rig is big enough, you could even put in a small fireplace with a gas heating element. It just depends on your individual tastes and what you want to do.
Before You Can Begin Winterizing Your RV, You Need To Have A Plan:
It's like anything else out there, first you must determine what your plans are before you can take action. This page is going to attempt to give an overall view of some potential areas that may need to be addressed before winter sets in. If you are a snowbird, life is simple. It is a question of just putting the shorts in the top drawer and filling up the tank... your outa' here!
What if you want to just park the thing, but snow and ice are coming your way? Different scenarios have different solutions. Let’s break things down a bit and attempt to clarify this subject of winterizing an RV.
If You Want To Park It And Let The Snow Pile Up There Are A Couple Of Things That You Should Pay Attention To:
To begin with I’m going to assume that you want to simply park your Class C Motorhome and let winter come your way. In this situation, there are a couple of things that will need to be accomplished before the cold weather comes.
First of all, you will need to insure that your
various water pipes, valves and holding tanks do not freeze!
There are some issues with how to prepare the engine, drive-train, and tires for harsh winter conditions... and you will not want to overlook your batteries.
This page is not intended to be a comprehensive checklist for all of the winterizing RV scenarios. This page is only an attempt to showcase some potential problems and is not intended to be a conclusive resource on this issue. For your protection, please consult your owner’s manual for specific winterizing RV procedures as they relate to your individual Class C Motorhome... we cannot be held responsible for any damages.
Life Wants To Live... That's Ok, Just Not In Our Class C Motorhomes:
Critters can be very opportunistic... that is a polite way of saying that they can be a pain in the butt! So what can we do to protect ourselves from these invasive creatures?
I don't think that all winterized Class C Motorhomes will have every insect, rodent, or spider known to man trying to make it their cozy home. But, you will probably have at least one or two different issues with these pests.
In my area of Sacramento, Ca, I have issues with mud dauber wasps. These are the black and yellow wasps that have thread-like waists... not fat like a bee.
The good news is that these things rarely sting... if left alone. They will, however, attack if you are attempting to destroy their nests. They are solitary. That is, a queen will build her hard mud nest and stay isolated.
They have no social groups like the yellow jacket that is very protective of their colonies and will attack just because they can... you might say yellow jackets have an attitude.
The bad news is that mud daubers like to build in places that cause motorhome owners problems... like heater vents. My mud daubers like to build their nest in my awning enclosure. However, they can choose just about any spot that is convenient for them.
Your best bet for eradication is to simply apply a commercial aerosol spray into there nest. This is best done at night, and then you want to leave the area. You could get stung, so cover up your body as best as you can.
In extreme cases, you may need to have a professional pest control company deal with the problem. They have access to an insecticide dust that has proven to be very effective.
Oh! Another thing... during the cold season in the winter months you can remove their nest without harm... the problem for me is that we don't really have a 'cold' winter in Sacramento... it just rains a sometimes.:>)
Lots Of Things Want To Make A Home In Your Recreational Vehicle:
Mice, or even rats, can be an issue... heck, so can skunks, squirrels and raccoons. I have all of the above where I live, but they have yet to mess with my motorhome. These bigger critters will go through screens to get into your rig. So if you leave a window open to help vent the motorhome, be aware that you may have uninvited guests.
If any of these animals get into your rig, they will build a nest by using your curtains, pillows, cushions, etc. They do this by chewing them up and organizing the material according to their taste.
You will probably have the most issues with mice. These little buggers can get into just about anywhere. If they can stick their head in through a hole their bodies will soon follow!
About the only thing you can do is to get under your rig and winterize against these critters by plugging any hole that you can put your little finger in. It is not that big of a deal... just get a good flashlight, and you should only have to do this once... if done properly.
Let's see, oh yeah... spiders! Spiders like warm dry places too! I'm thinking that you will not have a real issue with them getting into your rig. At least they haven't done that with me.
But, they do like the undercarriage, and they seem to be attracted to propane. This stuff is kind of like catnip to spiders. So, they hang around the propane tank.
If you take your tank out of the rig when you winterize, be sure to put caps on your hoses, or you may find a wad of spider webs next spring.
Ants may be an issue. Like all of the above, they will be looking for food. So, remove anything that looks like it could be a food source. Left over cookies is something that is pretty obvious and must be removed. However, toothpaste, or even soap could be attractive to some critter. Be safe, take EVERYTHING out of the rig.
The best way to prevent an ant invasion is to use an Amdro Ant Block or an Orthene WP. It seems if ants ignore the Amdro, then Orthene does the trick. Unfortunately, it is a trial and error kind of thing. The point is, use an ant block that takes a poison back to the colony and kills the queen. If you do not do this... you will have continual ant problems.
Heck, Even Water Wants To Get Into Your Rig:
There is also the possibility of an invasion of mold or fungus. There are lots of things to think about, but actually, most of the stuff that needs to be done can be accomplished in a couple of hours at most.
You can also have a professional RV maintenance facility perform a winterized check list for your home on wheels. This is not a bad option if you want peace of mind.
Mold is something that can sneak up on you... and you really don't want to have the stuff around. It is much easier to prevent mold encroachment than to clean it up after it has established itself.
Mold likes moisture. Keep moisture under control, and you will keep mold under control... pretty simple really!
All Class C Motorhome owners have a high awareness (and dread) of water leaks resulting from rain and/or snowy conditions. This type of leak will most likely
cause a dry-rot condition.
Condensation is another moisture bearing event that needs to be looked at. If you button up a Class C Motorhome for the winter and do not allow for moisture build up, you could have a ‘fuzzy’ motorhome by next spring.
All you need to do to prevent this is to keep the air dry inside your home on wheels. This can be accomplished by simply using a product like Dri-Z-Air or Damp Rid .

Dry-Z-Air Chemical Absorbent Kit
These products help accomplish the winterizing process and can be found at most RV supply stores... they even have the stuff at WalMart. Simply follow the manufacturer’s instructions, and they will draw the unwanted moisture out of the air that is caused by condensation.
Another idea, if you have easy access to your Class C, is to put some type of heat source in the unit. A simple incandescent bulb may do the trick. A small heater could also work, but it is risky business due to the potential fire hazard. This type of solution does need to be monitored closely.
I typically winterize my Class C by relying on chemical absorbents like those mentioned above. It works just fine. You have to replenish the supply and get rid of the accumulated moisture on a regular basis. How long it lasts just depends on how much moisture is in the air.
Some folks recommend a plastic tarp or cover to help protect your rig. Well, in theory, this makes sense. However, if you use a material that cannot breathe, you will have created a moisture trap that will create condensation.
This will cause… guess what… fungus. So, just be sure that if you do cover your rig, make sure it can breathe so the condensed moisture will evaporate!
To sum this up, you simply cannot park your Class C Motorhmome at the end of the season and expect to have it in
good working order next spring.
It's okay to let your rig "go to sleep", but you do not want it to go into a "coma" due to neglect!
