Hi Terese!
If you're trying to figure out a price to set for your Airstream, you might try checking out
www.vintageairstream.com under the section for determinging price vs. condition. He really breaks down some of the important factors for you. But, I know from my searches in the San Diego area, that many units around locally run on the higher end of the price scale. Something to keep in mind. If you have the time to watch EBAY for a while you'll get a hang for what units like yours will sell for.
Good Luck!
