Hello from Colorado: Welcome to the Airstream community. Hey, these forum participants are only opinionated about tow vehicles, hitches, tires, and winterizing. And maybe many other things too.
I have participated here for many years and find answers to my questions and enjoyable reading about the vintage Airstream hobby. Your 77 Sovereign
31' looks great. Has it been renovated as well as polished?
I just purchased a 75 Overlander 27' that I'm working on now. It has lots of needs, but I believe it will be a "like new" Airstream when I'm done with it. I may be able to recover the new items I put in it; for example, new axles, shocks, bearings and brakes.
Some previous owner painted a blue stripe on my trailer. It is a pale blue. Actually I kinda like it. I'll decide much later if it needs changed.
Jump right in and stay up all night reading about the Sovereign
