Both the interior and exterior skins on the door have migrated towards the latch side, especially at the top. Based on Michael's experience noted above I'm wondering if the door sticking problem might not be a possible expected symptom of the skin moving. If the skin moves in that direction the door will tend to stick, you file it off so it works but the sticking comes back as the skin continues to move. Since my door skin has moved much more at the top, this could also explain why the door is bent somewhat outwards at the top on the latch side; it got stuck and someone forced it and it bent.

If as appears likely the case with my coach, too much foam broke the double sided tape bond, the door skins moved toward the latch, binding of those skins with the door frame resulted, forcing the door against that bind bent the door, and continuing this pattern expanded the breaking of the bonding by the tape. One way of testing this logic on your coaches is to do a careful inspection of the gap between the door hinge and the front edge of the outer door skin. In my case at the bottom the skin is tight to the hinge and at the top there is a gap. Once I paid attention to it it was really obvious, I just never paid close attention. If this applies to other coaches as Michael's posting suggests, the binding is not caused by heat alone, it's caused by skin movement together with heat. The heat makes clear that the skin has moved, especially if this is a problem that emerged as the coach aged.
