Crack in corner of rear slide

[TwoElkhounds]

I discovered a crack in the fiberglass at the upper corner of my rear bunk slide on my 2016 323BHS. Upon further evaluation, I also noted that the paneling inside the fiver is also cracked in the same place, pictures attached. This leads me to believe that I have a wall frame issue, possibly a broken weld in the wall bracing. I think this is the only thing that would cause both the exterior fiberglass and the interior wood paneling to crack in the same location. Agree?? Suggestions?

Yep, I would speculate the same. Likely a fatigue fracture. Put the slide out partially and grab ahold of the wall through the seal and see if you can easily wiggle it back and forth there. If so, I'd be on the horn with GD for a fix because you can't really sleeve there with the header. Probably a sidewall replacement to do it right versus obvious plate patchwork.
