I own a 1997 29 ft single slide Dreamer, which was the lower cost version of the Alpenlite (they no longer make the lower cost nameplate). I am satisifed with the unit and manufacturer. The only maintenance items in 6 years have been 1) replacing the Goodyear Wrangler tires with Michelin XPS Ribs (steel cord sidewalls), 2) replacing the Dexter axle spring nylon bushings and hangers with greasable bronze bushings, and 3) regluing a 4-5 foof diameter bubble where the rubber roof separated from the plywood.
The Rubber roof repair was this weekend, took about 6 hours, hope to get the 10 plus years advertised for rubber roofs.
If I was upgrading to the double slide 29 ft that the wife wants, I would get an Alpenlite.
