Hi all. So, I had an issue with my pup this past summer. I am talking about the upper door section where it hinges to the roof for closing down - not referring to regular door hinges for going in and out. Now, when I fold up my camper, where the door attaches to the hinge and plate near the ceiling (to secure door for travel) it keeps popping out of the rib that it snaps into. The top of the door has a groove. The part attached to the trailer has a rib attached to an aluminum plate with hinges allowing it to hinge and attach to the ceiling. I put the rib into the groove and secured my upper door to the lower section and during normal use of in and out of the trailer it is fine. But when closing up, the son of bitch keeps popping off and I have to lay the door down in the camper instead of up on the ceiling. its becoming a pain to re-secure the door every time we open the trailer. Anyone have any ideas on why it might be doing this? maybe the groove has opened too much?
