Exterior Panel Deformation
I have a 2020 Thor Chateau that is still under warranty. On the back exterior panel above the center rear light, the panel is show inward deformations where it curves to meet and attach to the roof. The dealer indicated that this is a cosmetic issue and did get Thor to agree to replace the entire back panel. My concern stems from the fact that the dealer indicated that when they put in the new panel and curve it at the top to meet the roof, that the same issue could happen again. Claims there is no support behind the panel at that point.
Is this true? If so, why would it not be a manufacturing defect with a process to fix it permanently.
Has anyone else had this issue. I have attached two pictures taken today that should highlight this problem.
Thanks for any and all ideas.
