Chris, I also echo Carol regarding your cushions/bedding: I set all my cushions up on their edge, take blankets into the house, prop open all the cabinet doors, hatches, fridge
, closet. I also leave the small kitchen crank out window slightly open for air flow. Keeping air circulation really helps. In my small 13' camper I use 2 Dri-z -Air baskets. And as Carol said, as the crystals pull the moisture out of the air and collect it in the bowl, you have to empty it out and refill the crystals. I check once a month...will depend on the moisture in your area.
Also regarding a cover --- for the first few years I did not have a cover and had it parked at a storage facility (had nowhere to park at home). It go blasted by sun and weather and rain, etc. It was hard on it, especially the rubber seals/gaskets around the windows
. If you can't get a cover, at least cover your tires
and treat the window gaskets often with UV inhibitors -- 303 or something like it. Keep it waxed to protect the gel coat for oxidation....
Alrighty.... and thus, my deep words of wisdom end....(again) Selah...
