I always wanted an Airstream too, so last year I got a great deal on a '64 Safari 22' for $5000. Since then I've replaced every mechanical thing in it except for the AC, which after I freed up the frozen motor and got all the hornets nests out, actually works quite well. I've also replaced the cushions and drapes, polished it and got the banana wraps straightened. I added a microwave, TV and stereo. Somehow or another, I've got nearly $20,000 in this now and it still needs a new floor and some of the cabinets rebuilt. I love it, and am really looking forward to going to the Pismo Beach Rally on Friday, but these things aren't cheap. Good luck with your Overlander.
