Hope you find what you are looking for...one idea would be to stop by a local rally to check out lots of different models, ages and layouts to narrow down your search. Then be prepared for a road trip to go get one if you can't find one locally. By going to a rally, you will meet people who have Airstreams and 'put the word out' that you're looking. Alot of pristine units sell by word of mouth...
soooo, what better way to get in the loop than to meet people that already have them? Get them involved in your search! You
never know...
Also check the classifieds section here on the forums (tab at the top) and local dealerships. Good luck in your search...have fun!
