I have a 2018 Hawk. On my second trip I was heading home and went through a pretty severe t-storm that put multiple dents in the roof. The solar panel is still working fine. Given all the grief that the Overland Solar panels get on the forums, I've pretty impressed. P.S. I did talk to FWC about replacing the roof under an insurance claim, and they advised that if it wasn't leaking, probably would be better to just leave it. Considering that I live in Oklahoma and I would have to take it the factory and leave it, I can imagine the cost would spiral pretty quickly. Still no leaks, so I guess they were right.
