Well I owe you an enourmous thanks. I did as you mentioned and we successfully hit the road late last night (albeit a few hours behind schedule!). We just landed in NoCal and had a great drive. With one exception...
Apparently a rock from the road hit the moving panel of the drivers window and shattered it on contact. Scared the hell out of us, but we're fine. Will I be able to have any ordinary auto glass guy replace that or will it require ordering a special Airstream part? The handle flew out the window, so that's going to have to be replaced. But the glass appears to be standard autoglass, slightly curved in one axis and set into the felted slide channel.
And again, thanks!
