storage

Yes, they breathe. I like my Goldline cover from NationalRVCovers. Expensive however.

I used one for the last 3 winters with no problems, left the bathroom vent open 1/4 inch. Doors on trailers don't seal all that well so there was always some air movement. I leave all drawers and cabinets open and any under bed or seat storage is also open.

what happens to the rubbery roof antenna?

Fisherman- what brand do you use?

thanks guys your great help is very much appreciated

Campers covered outdoors in 2 of the wetter environments. South central AK and coastal PNW. No issues with moisture retention.
I could see a potential issue maybe in somewhere like the SE part of the country where a very wet environment is combined with warm temperatures. Unlike my experiences where wet generally also = cool or cold weather.

I had the Gold Shield one, the only thing I added was a very light box made of 1x6 cedar, bulged top, to cover the antenna and couple of old cushions between the antenna and bathroom vent. Bone dry up there.
