Go to
www.airstreamforums.com to get started with your research now. You will need to be prepared before you make the decision to buy. I was a member of the airstreamforums.com for two years before we made our purchase and that is about the average for those who purchase vintage trailers, too. In fact, my family attended two forum rallies before we purchased our Airstream and got to know a lot of the members face to face. There is a forum rally next week end at the North Georgia Fair Grounds in which 34 members will be meeting informally for the week end. There will be folks from as far away as New Mexico and a snowbird couple from Canada stopping in on their way to Florida for the winter.
You will be surprised at how many parts are still available. All of the major appliances/systems are still available new except the stoves and refriderators that were installed in the 1950's. If you want them, you can find rebuilt. Several years ago Airstream decided to divest itself of all of its new-old stock and a company in California bought all of it. They still have a tremendous supply. If they don't have it, they know where to get it. There is also a company at
www.vintagetrailersupply.com that stocks parts for various vintage brands. There are a variety of vintage trailers that have a "cult" following. There are also a number of companies that reproduce parts that are no longer available.
If you are not looking to restore, but are desiring to customize and renovate to your specific needs and are more interested in a shell with a functional interior that is custom to your specific taste and needs, then all of the parts you need are redily available. Many owners do exactly what you are talking about. A fellow architect that I know recently picked up an early '60's 22 foot model Airstream that he intends to gut, add a gray tank (they didn't have them back then, only black tanks), do a couple of other customizations, and finish off in an Art Deco/University of Tennessee theme. You can do whatever your imagination and skill levels will allow. Many people do partial reno's and begin using their Airstreams soon after purchasing. They renovate during the off season and use what is functional during the camping season. Each year they get closer to their goal without having to wait for several years to use it or shell out all of the expense at one time.
For me, I have two left hands and they are both all thumbs so renovation/restoration was not something I wanted to take on so new was what I wanted. My wife has decorated it with a Jimmy Buffet/Caribbean Island/Jungle/Safari/Mickey Mouse theme (I know it's a lot for a 30' trailer, but it is subtle and it really does work). There is a lot you can do with an Airstream.
Good luck in your research and in your quest for the "pperfect" Airstream. I'll keep an eye out for you on the forums or send me a PM to let me know if you use a different alias on that forum. BTW, there is a search function that you can use on the forum directory that will allow you to find other members in your state and you can see if there are any members in your community or immediate area if you need local advise. There are also members that will do a cursory inspection for you if you find a unit you are interested in that is too far away for you to inspect yourself. They can tell you if it is worth the trip for yourself to see or if you should pass without making the trip. It is an a thread entitled, "So you want to buy a trailer three states away". The people on the Airstream Forums really are a good bunch of folks. They are just as willing to give advise and be helpful as the Dis'ers are. Most have "been there, done that."
There is also a classified section where you can view adds from members who have Airstreams for sale. You can also go to Airstream's corporate web site. They have a forum also and they have a classified section, too. These two classified sections will help give you an idea about prices.
As you can tell, I really do love our Airstream and have made many good friends on the Airstream forum and really do support it.
