It's 217 miles to Out of Doors Mart
in Colfax, NC. Of course only an Airstream dealer with a good service center will be willing to take this on. SOB RV dealers tend to think we Airstreamers are too picky -- like we don't want a fiberglass panel sillyconed in, want it aluminum colored, and other unreasonable delusions...
Talk to Out of Doors Mart. They might know if there's somebody good closer to you. You might get an estimate for settlement by emailing photos to a repair shop. Or check airstream.com and call dealers closer to you.
Best wishes -- let us know how it turns out! It's sad and upsetting to get these storage facility dings.
