Sabre and ADCO cover

[ns-sabre]

Hello, Wondering on experience with Adco cover. MY story is a litle long as I have roof problems last year ( brand new) as per another thread. dealer and Forest river agrred to replace rubber roof last fall. I covered with breand new ADCO cover. When uncovered this spring i have several spots like the attached were the black rubber is showing. Dealer steh covers fault in the wind and they do not reccommend covers? Thoughts /comments. One item of note as you can see in my pic, and I looked at alot of other units on the lot... All Sabre's have this very sharp (90degree) edge. Isaw mine when apart. Basically teh edge of the particle board, both a 90% sharp angle, and very rough finish with imprefections/ spurs in board. When the rubber is pulled over this it creates alot of bumps and roughness along theat edge for both things like the cover to rub on and for pressure from below to push up at these points. In looking at most other brands they have a nice "rounded" edge, looks like they use a piece of moulding of a plastic rounded cover that creates a nice smooth rounded edge for the rubber roof, and would prevent this kind of issue. Simple design flaw. Any others with good/bad experience with cover and this roof edge? Thanks
