Hi and welcome to the forums. If you are looking for manuals
, you can get reproductions from Helen Davis at Secretarial Services, PO Box 484, Sidney, OH 45365 (937) 492-8885. High Quality reprinted Service and Owners' Manuals are also available from the Airstream Store at www.airstream.com
look under books. If you don't see the year(s) you need contact Airstream.
On edit - it looks like they do have an owners manual available for your trailer, listed on the website. Cool!
