Sorry about the accident but I'm glad you're okay.
Martin Truck Center is a Freightliner dealer but doesn't have very good reviews (typical of a lot of Freightliner dealers). I doubt that they do body work, however.
Let me take a look in my log notes and I'lll get back to this thread if I find anybody else you might consider taking it to.

Well, according to my journal notes, I talked with a guy who had some minor body repairs on his Newmar Dutch Star(?) at Truck N Trailer Equipment outside of Lake Charles. This was over ten years ago, however, and i just have sketchy notes on it. He said a tree fell on his motorhome and it had some fiberglass body damage. He said these guys did excellent work.
The good thing about them is that they also do mechanical work on trucks too so in all likelihood, you might be able to have them do everything in order to get you back on the road in order to take it where you want later. I suppose you can tell them that ..."just do the minimum so it's driveable as I have somewhere near my home base where I'd like to take it later..." etc. Not sure if the place would be acceptable to Progressive or not, however.
