MSRP of each trailer is a way to start comparing. Better materials like nicer grade of furniture, solid surface countertops, porcelain toilet, better grade of floor covering, solid wood cabinets, etc. will be part of the difference. As far as build quality, every manufacturer turns out average built stuff, once in a while they build a jewel where everything is perfect, and the next unit off the line can be a lemon. I have owned two Coachmans now and they are built to a price point. Vinyl over particle board cabinet frames etc. One had a single problem with a window screen that the dealer took care of. The one I have now has had a few problems not the cause of Coachman. The vendors of the equipment took care of those problems, but I did the labor at my request. Lots of people will tell you to run away from Coachman, and cry you need brand zzz or no, you need brand xxx, but look at the owner's forums and see if they are really better than any other.
