our designer series is going on year #4, used anytime the trailer isn't going out for a few weeks, summer and winter. It has a few punctures from sharp things like the steps but nothing like what you show. Actually, the Tyvek roof section has more holes I had to repair, most from birds, but some where things like the AC cover screws wore through.
Actually the sides are in wonderful shape virtually no wear.
But then we don't get lots of sun. I'd give Adco a call and see what they have to say.
BTW the best way I found to repair tears is to put a patch of the Adco adhesiver repair material over the hole then cover it with awning repair tape. Holds much better than the adco adhesive.
