A lot of the fiberglass trailers are decently made - Scamp, Casita, BigFoot, EggCamper. Lance are decently well made. Northwood has had a good reputation in the past, but there appear t be some questions now. Haven't heard from someone that has one though. AirStream are still reasonably well made. (BTW - all of these brands have something in common - they're all significantly more expensive for a given size trailer. Yes - you do have to pay more to get a well made trailer - it's an industry who's primary cost is labor.)
My trailer isn't bad, but that's more luck than anything else. :) I think I got one made on Tuesday.
