Yeah, totally get that kinma as I used Velcro at first to make sure it would work before I tried a more permanent way of attaching it. Velcro works, but holds the trim piece further under the roof edge. The Velcro got soaking wet and when the tent end is deployed, it pushes upward on the trim piece.
