The dealership just called me back after talking to Keith. The good news, according to what Keith told my dealer, is that this will not require a body shop, so he can take care of it. It sounds like Keith will walk his guys through the repair process, which could happen as early as next week.
Possible causes discussed with Keith and my dealer:
1. Loose turnbuckle + big bump
2. Tight turnbuckle + big bump
3. Not enough adhesive applied to the gel coat ahead of/during the fiberglass installation.
My turnbuckles are installed per TorkLift's specifications and I've never been off road with it, so I am leaning toward Number 3.
