Honestly, I'd get a couple other opinions, that seems insanely high to me. If the others are in the same vicinity and you don't really wanna get rid of the truck, you might see about withdrawing the claim (not sure that can be done). Around here, we have several PDR guys that work as independents and are very reasonably priced. Something like that (especially if you pulled the headliner down for them) would probably run ~800-1500 with those guys.
A coworker had ~5 dings in one door, a couple more in the other, a couple pretty good dings and creases in each bedside of his 07 NBS HD and got all that done for $350.
