We're starting our second season with a Mini-Lite 2109S. No leaks, no problems with it really. I would buy another Rockwood in a heartbeat.
One thing about the Murphy bed Rockwood models, if you have not already discovered, there is NO pass through storage. There is an opening on one or both sides where the pass thru access normally is, but you might fit a shoe box in the space there, that's about it. I considered the Murphy bed modesls, but lost interest in them due to the lack of storage -- wasn't acceptable for us.
Google Forest River forums and go there to find discussions of the model you are interested in.
Good luck!
