R'ving is full of things that can go wrong, as you stated. After touring the factory and buying a Riverside Retro and I honestly say they do try to build in quality. We have enjoyed our TT and had very minor things to add or fix. They are built in Lagrange, In. You can visit the Riverside website and also visit the Riverside owners forum for more information.
