Hello from Colorado. Welcome to the vintage Airstream hobby. You are right, these forums will be a great asset to you and your project trailer.
Disassembling the trailer is easy. My friend's Sovereign
that we are rebuilding this winter was in rough shape. Many, many repairs to make. But we are making progress a little at a time. Our project thread is right under yours in this Forum.
Take photos of stuff you think might be important. The design and fabrication of the new stuff is very time consuming, at least for me. We are up to our necks in alligators on our 76 Sovereign
project. I've spent two weeks just on the wardrobe closet in front of the bath. Everything is cut to fit.
Be sure to ask any questions you may have along the way. We all will help out where we can based on our experiences. It takes an Airstream village.
