It's not a brand of motorhome you hear much about. Never got popular outside of the Airstream community, for whatever reasons. They quit making the Class A model about 5 years back, after struggling with various sizes and styles for a number of years. The sizes were in the 33-36 foot range in the early 90's, dropped to 30 feet by the late 90's and then to the 26 ft arena in the 2000's. Now they are making some Class B vans.
This site has a wide selection of Airstream models for sael:

Sorry - I don't have any useful feedback to give on quality, chassis used, etc.
