Welcome David and Dawnell, and congrats on your Overlander!
the type of folding door you're talking about?
You're very close to the Tin Can Tourists Mt. Baker vintage rally
coming up August 14-17 in Deming (at the logging show grounds). Think about coming for the weekend or just for the day on Saturday!
Hope to meet you on the road one day, and good luck with your Airstream.
