to Airforums.com, Red! You found the right place to find out how to put your new-to-you Airstream in order.
Get used to the fact that if your TT (travel trailer) needs ALL that stuff done (and that is believable), it will take a fair bit of time and something over $3,000 in parts.
Or, you could get it done fast, if you are willing to spend more and use someone else's labour.
In the meanwhile, in your place, I would concentrate on making absolutely certain that you have NO leaks where water can enter the shell and degrade your prize. Use the Search mechanism and read read read! You're a teacher, so that shoul be easy for you, right?
And how about a few photos of the interior and exterior? We love photos..
