Being in Phoenix AZ, the sun destroyed mine, I could scrape the plastic off with my finger nail!!! After I put on a new one I protected it with an 2 aluminum pie dishes (they came in packs of 2, didnt have a use for the extra one so I used both), the tank cap holds them on. Since I have to park the coach (96 Monaco) always with the rear facing South (and the vents just let the sun pour in, it was also eating the ducting to the air filter) so I decided to use an old political sign to block the vents...works great; I leave it on for short trip but plan to remove it when I get on the Hwy. If you want pictures, PM me via IRV2...handle, arvowl Good Luck Paul
