Well, fancy meeting a fellow Coloradoan here. Maybe you live in the famous "4 corners" area. Welcome to these virus free Airstream Forums. These Forums are better than any owners manual seems to me. Vintage Airstream trailers are not too complex. You need some basic knowledge such as 12v
electrical, plumbing, carpentry, a little mechanics and some common sense. I just jump in, see how it was made, and then figure out how to repair or replace it.
Take a look at the Airstream Trailer Knowledgebase near the bottom of the Forums page. Find Trade Wind, or Tradewind (Airstream spelled it both ways over the years), then your model year. There you will likely find lots of information on your trailer, see photos of one torn apart, and get a grasp on what your trailer might need. Trigger warning, likely everything.
My first project trailer was a 66 Trade Wind. I thoroughly enjoyed renovating it. I spent maybe 1200 hours on it and maybe $12,000 in materials over those two years (part time). Here are a few photos of what it looked like when done. I was a solid travel trailer. I sold it for another project. Dumb huh? Maybe the photos will help you out.
