Condensation During Winter Storage

We have Max Air covers and leave our vents open. The biggest cause of condensation is a temperature difference between inside and outside. We also use three Dri-Z-Air pots, an air dryer like Ava mentioned and a few Bounce sheets scattered around. Never any condensation or mildew problems in the Great North Wet.

Ours like most, I suspect are pretty tight.
Cold outside, warm inside and people breathing, furnace and moisture drawn from around gaskets will condense on windshield any other surfaces, especially metals.
A dehumidfier is about the only real way, over weeks and months to protect it.
Set moisture level on unit and hose into sink or shower drain etc. Set the unit on a solid surface away from anything that might combust. There is always a chance with anything electric.
Cracked windows and letting the inside rest at close to outside temps will certainly help but there will still be too much condensation.
The reasons fabrics and cushions smell musty after being stored in the humid environment is they are musty and moisture condensed to some extent on and in them.
Perhaps some Manufacturers build a dehumidifier in but I don't know one.
We have as most had to turn on coach engine and let dash air/hear run to clear up windows and windshield etc, while parked.

We've NEVER experienced excessive moisture in any of our Rvs over the winters. Never gave it much thought..... Of course we've stored ours inside (not heated) for the last few years, if that makes any difference. This winter it will be sitting outside not covered.

Great, something else to worry about now! :E

Rock salt works also, Salt absorbs water.

I use a moisture dryer in mine over the winter. I used to use it on a boat but works well in the rv as well. It is a metal box that has legs and sits just off the ground. It has holes in the top and a small electric element inside ( about 75 watts ). It simply moves the air to prevent condensation. The air is drawn through the bottom and rises from the heat. It doesn't heat the inside but moves the air constantly. Camping World sells one like it that has a fan as well. Doug on the wet coast.

Leave vents open with vent covers on them.

Heating it is an invitation to mice. They like a nice warm nest.

I'm in S Ontario where the temps can easily hit -25C, with considerable amounts of snow, and have always covered our trailers with a breathable ADCO cover, some winters with the vent(s) open and other times with the vent(s) closed and desiccant such as Dri-Z-Air distributed throughout the trailer. Personally I prefer the latter and do find a considerable amount of condensate in the collection bowl when I check the trailer each month during it's winter sojourn.

I've not heated it but was considering it this year. We have a heater that keeps it just above freezing, at least that's what it says, hence the question. Heading south in Feb so things are a bit different this year.

Won't be covering it this year, if we get much snow it'll be a bear dealing with the cover. I have a Maxxfan with it's rain cover s I can leave it open.

The only time I had an issue was when I completely tarped it. All my cabinet knobs were pitted. I now use a RV cover with vents open, don't heat it and have had no problems in 5 years. (diff. rig) The cheap tarps do not breath.
