Triton Prestige Trailer Enclosure Repair

[stick]

I was so bumbed yesterday when I got home and was backing in a Triton Prestige enclosued trailer in my back yard, and I wasn't watching and dented and scratched one of the panels on a tree branch. I said "oh shucks" (or something like that) when I saw the damage. This trailer has sections of aluminum "skin" in the form of panels, and it looks like there are screws holding each section on.

Does anyone know, can a panel easily be replaced? I'm guessing it's not cheap for the aluminum if it's even available from a dealer. I'm not interested in a "home grown" solution, just a factory replacement part.

I thought I'd start on this site, and if no good ideas or knowledge, I'll then call the Triton dealer.
