Hello John D
My father-in-law used to have a sail boat docked in the Berkeley Marina (San Francisco Bay) and all of the sail boat owners would hang a 40 watt (+ or -) light bulb turned on inside their sail boats all the time when they were not using the boat. He had his hanging in the walk way area from a thick piece of string.
The heat from the bulb created enough heat and convection inside it really kept the moisture and mildew to a minimum.
I don't know if it would work in a camper, but I don't see why not.
Maybe worth a try for those long, cold, wet Winters.
======================================================
Storing your camper can be a very big problem. Know your local weather statistics. By color, the attached map shows Alabama with more rain than Arizona. It is a generally true statement that stored campers have more mildew in Alabama than in Arizona. But it is not that simple.
In Alabama, if my camper is stored outside during winter, which is our wet season, I cover it with clear poly sheeting/visqueen tied down. In a few months, the visqueen develops leaks. It becomes brittle and deteriorates. I try to go inside my camper as often as I can think about it to check things. I replace the visqueen when it goes bad. When I see mildew, I use a mixture of Clorox, detergent, and water to kill it. I have a large computer muffin fan running inside the camper all the time. This is not a perfect solution, but it sort of works. It would be much better if I stored my camper indoors … or used it regularly.
I have used canvas to cover my campers. Canvas does not work in Alabama, too much moisture. Tree sap is a problem in Alabama, particularly with canvas. The only exception in the use of canvas is to construct a tent to store your camper in. Tents don’t work well in a place with tornados and thunderstorms. I built a shed with a galvanized steel roof. The wind blew the rain under the sides. A tornado finally got it.
Alabama is used as an example herein because it is different from where most of you live. We have different storage problems from where you live, just as each of you have special problems with storage in your own area. Do the best you can, and good luck.
