Who to believe?

The conundrum I am going thru presently is whether to cover the RV during all the months I am gone. The covers are expensive, and there is the possibility that some moisture might get trapped inside or outside while covered up.

we are gonna cover ours.. have the cover just need to put it on.. i figured keeping the uv rays off the roof as much as possible will only help. cover was only about $250. hell the darts cover cost more then that.. its well vented so i don't think moisture will be a problem... i put the same cover on the inlaws trailer at the beginning of november and we were just out looking at it earlier this week and its fine.. no mildew or anything. as cleas as it was when i put the cover on..

at the very least get the tires up and out of the dirt.. and cover them..
