I can recommend two facilities with whom I have had very good experiences. The first is a regular Airstream dealer while the second is a brand X dealer who has been quite helpful.

Fogdall's have maintained my Airstream since shortly after I acquired it in 1995 and also have been my maintenance source for the Argosy as well. The quality of their work has been beyond reproach, and I have always been very satisfied with their facility.
Since my property where I store one of the trailers is more than 700 miles from Cedar Falls, I have found it necessary to have a number of reparis handled nearer that location. For the last seven years, I have been very pleased with the service offered by Kamper's Supply in Carterville, Illinois - - they are a Brand X dealer, but aren't opposed to working on an Airstream product. They have helped me out with brake work, winterizing, plumbing repairs, etc.
