Been using a ADCO on our Class C in sunny California and love it. Helps keep the harmful and paint fading UV light from doing its damage. It takes me all of 15 minutes (or less) to put on. I get it started by having the cover (our coach is 22') bunched up on the hood/windshield area and them my wife uses a rake handle pole to get it started up to me on the roof. Easier than one thinks. Money well spent IMO.
