I had one on my TT and it lasted 4 years and I thought it was great. At the end of it's life the side facing the sun was shredded and the side in the shade was like brand new. If I knew then what I know now I would have rotated it every so often when reinstalling it. That would have put the access panel on the wrong side, which may not work for everyone.
Looking at installing an RV Carport now.
