Hi dlscott425 - Welcome to the Forums!
This sounds interesting if somebody cared about it recently enough to put in a fridge 2 years ago. Better yet if the air conditioner works! Nice!! All these projects take more work than we think initially. Spend lots
of time here. Oh, there are so many systems...
If you don't have an iPod I would still recommend listening to The Vintage Airstream Podcast - Home
while you're sitting at your computer. Go back to episode 22 in their archives -- Tim picked up his Ambassador on that episode. He has just completed his rebuild -- with a lot of unbelievable sponsor contributed merchandise -- but the blog on theVAP.com can give you an idea of all the steps.
