I was in too much of a rush last night and should have gotten the link to the Alpine Coach Association for you. Here it is:
Alpine Coach - Technical Information
This is the page with the links to all the brochures and tons of technical information and manuals. Yes, the one poster is right, the manufacturer has gone out of business. But, when you think about it, almost everything except for the steel frame is made by someone else (HWH hydraulics for the slides and jacks, Dometic for the frig, Atwood for the water heater, etc.) And they are all still around.
The other thing, maybe the most important thing, is that the Alpine handles like a dream. We're talking one handed, relaxed driving. No scary winds pushing you sideways when a semi passes you, etc. As a matter of fact, one of my favorite trips is from Fresno into Yosemite National Park on the curvy Hwy 41. It's a blast to drive that road.
Alpine is considered a hi line (meaning higher end) coach. A similar high end coach might be Country Coach. I don't think the Fleetwood is in the same category.
