Like you, I had a fairly dissapointing long list as well. I had a few choices. First, drive 350 miles to a dealer that was by most accounts well qualified or drive 350 miles to the place that built it, Airstream in Jackson Center, OH.
I opted to go to Jackson Center. It was a great trip, nice folks, work done was excellent. Roger Williams in Texas is also well known and respected. I've seen a number of custom work done on Airstreams by that dealership and you'd have been hard pressed to know it didn't come that way from the factory the work quality was that good. Andy from Inland is great, but he is a Star Trek from your location. You'd spend 3x the amount in gas compared to going to Texas or Ohio.
Computers manufactured by companies such as IBM, Compaq and millions of others are by far the most popular with about 70 million machines in use worldwide. Macintosh fans note that cockroaches are far more numerous than humans and that numbers alone do not denote a higher life form. -NY Times 11/91
