I have an 8311WS in a Signature Series and love it. Seems to be built very well compared to our last camper (Coachmen). Although we never had the first problem with our Coachmen, you can just tell the Rockwood is better built. The only problem I have come across with our Rockwood was every single water connection was loose from the factory. During the walk-thru after we bought it, water was leaking at the connections and they had to be tightened. After a couple hundred miles of towing, I tightened them a little more for good measure and all seems well. The only thing I'm worried about is a rock catching the front windshield, fingers crossed........
