Well I took the cover off the RV. Immediately I noticed where the cover has rubbed against the side front and back and it looks like someone took a brillo pad to the bumper area. I took it to CW in...
Also consider either pitching the cover completely or finding one where they will warranty any damage done by their cover.
I had the same thing happen with a classic Mercedes and I was not happy. I had paid a pretty penny for the best cover I could find and the manufacturer told be it was my fault for parking it in an area susceptible to winds.
