Initially we were pleased with the fit, strapping/rope system, and breathability yet water resistance of the Aqua-Shed top panel. However, we found the same dismal durability problem others have. The first cover didn't make it through winter. We requested a warranty replacement. The second cover has already torn again after less than 6 months of intermittent use during the camping season. The issue seems to be concentrated with the top panel material which not only tears but turns to a powder as it disintegrates. Incidentally, the trailer does not have sharp corners or edges that are causing the cover to tear. In both covers we received, once the top panel started to tear it was a matter of days before a quick progression of tears appeared along with the powder.
