I've been covering all of my coaches (1 TH & 2-A's) over the years, all of my RV covers seem disintegrate after about 1 - 1.5 years of usage in SoCal no matter how expensive the cover is. So, I just buy a new $200 cover each time. I'd rather the RV cover disintegrate than have the gel coat look terrible from sun damage. I was looking at building a portable garage for my coach, but I don't own the land where I park my coach. As for a covered storage facility, they are pretty pricey out west.
