I don't know anything about the Rockwoods, but I have a 2010 Surveyor 186, which I have seen listed lengthwise in different ways, sometimes 19-plus feet, sometimes 20. If this is the one your're looking at, I will be glad to answer any specific questions you have....if I know the answers. In the 10 months we have had it (it's our second camper), we have been very pleased with the quality. There were a few cosmetic issues that the dealer fixed for us prior to purchase, and we now have a sometimes leaky commode valve, which is a Thetford issue that will be fixed under warranty next week. The other appliances are Magic Chef, Dometic and Suburban, and all have worked very well. As for build quality, nothing has fallen off or come loose and nothing has leaked, other than the commode valve.
