If it were me, I'd schedule an appointment with the nearest Airstream Dealership with a travel trailer service department. According to Airstream, Inc.'s web page
, the nearest Airstream Dealerships for you while you are at the Death Valley '49ers Annual Encampment
(Wednesday, November 5 - Sunday, November 9) at Furnace Creek, CA, 92328, are:
Airstream Los Angeles
(approximately 170 miles away)
Airstream Orange County
(approximately 193 miles away)
The above Airstream Dealerships have Service Departments and appointments can be made online.
When making an appointment, it would be good to give them the details of the window to be replaced to make sure they have the part available when you arrive for service.
Good luck with this,
