I don't know but I'm hoping for some experienced answers here. I'm looking for one. I have no shade where I live and where my camper is stored. This means the sun will beat down on the roof forever and I'm concerned about UV damage to the roof (and caulking), and subsequent leaks.
I have owned a couple popups and a TT and have not had good luck with the Adco cover before and I most likely will never buy another. Or anything like it. I am looking at Calmark and have submitted a price quote request. They use Sunbrella material and that should last...I hope. I have no idea what to expect on the quote though.
