Kinda sorta related, but I wondered if someone is working on a database to hold all kinds of specs for all years of the Airstream. Certainly a need for such a tool. It could group years, place of origin, internal specs with measurements and reference photos of original configurations.
Your windows would just be one small aspect of the large collection of data.
I've seen a few sites that tell you general information, such as
Vintage Airstream Photo Archives
but we could use the nitty gritty. A few rallies and some data collection would get a large chunk.
Maybe should be a new thread.
