[CarbonFun]

Thanks for the info JRTJH...
All the damage occurred during the second part of our 6 week trip around the county totaling about 8500 towing miles. Seems so strange that a sealant like dicor would peel up off the rubber roof in a solid sheet. Although it would be great to have Keystone warranty the repair, I did read your response and it's obvious Keystone does not really stand behind their product or its construction. That is very unsatisfying.
Our Carbon is winterized and resting nicely inside our shop at this time. I will grab a few tubes of dicor and spend an afternoon on the roof.
