3051S Slide Out Trim Pulling out

[dcogs15]

2013 3051 with 15k miles recently had the front Schwintek gear replaced (broken?). Dealer also replaced the vertical trim piece. Since then, the lower 3 screws have pulled out when the slide is retracted and seats against the bulb seal. Dealer just added 3 large rivets that appeared to pull the trim tight against the fiberglass wall. After driving 30 miles the screws and rivets have again pulled out of the wall. The bottom screw is completely out, the next one up is approx 1/2", 3rd one is approx 1/4". I have seen other threads with similar issue. Does anyone know what the cause / fix is? Dealer tech is trying to contact FR factory, but I'd like to hear from other owners who have been through this. Sorry for one pic on its side, I can't get it to rotate. Thanks

Looking at your pics it appears that the wall or the slide box are not square to each other, I think there is more to this then just loose rivets or screws. Wish I had a better answer for you.
