Yeah that's kinda what I thought. it sort of looks as if the seal got folded over the last time the slide was brought in instead of fliping over to ride flat on the roof and now that the slide is out the rubber seal seems to be retaining the memory of being folded over so the edge that normally sits on the slide roof is curled upward and the seal isn't sitting down tight against the slide roof. If you think of a windshield wiper how when it travels the wiping edge goes with the windshield I don't know if that made it any clearer or not. I'd post a pic but don't know how or even if possible on this forum. The center of the seal seems normal only the ends are effected
