Same answer. Search this Forum for RV Cover and read on. I can't imagine how difficult it is to install, remove and store one of those roof and four sides covers!
We use a Sunshield tarp for the roof and whatever hands over the sides. Easy on and easy off BUT one has to get on the roof to install it. If you have a REALLY big rig use two smaller tarps and overlap them a bit.
