"Reasonable reputation" includes most RVs unless you're really shopping from the right side of the menu or the really high dollar ones. Regardless of who builds it, a lemon is going to slip through from time to time and you can only hope it's not yours.
We're on our second Rockwood product, first our HTT ROO 23SS and was wonderful. This last year made the move to a 2013 Rockwood 2604 and have no problems. When I say "no problems", we had a hinge on the bathroom cabinet get loose and DH fixed it with a toothpick to fill the hole, some wood glue and put the screw back in. We don't consider those to be problems, because most everyone has them. Overall, the major components were and are trouble free, the quality has been very good and we would likely buy Rockwood again, if we were making a change which we aren't. What model are you looking at?? You might come up with specific info for that model that would help.
