We just purchased a 2011 HD F350 Diesel, quad-cab with short box with the intention of getting a Big Horn 3670RL. We had been looking a other 5th wheelers, but once I came upon the Big Horn, I was sold on the quality workmanship, the engineering, and floorplan that fit what I was looking for. We will be purchasing this within the next year, have to wait for my wife to retire as we plan on using this RV as our second home away from Wisconsin's long winters. I'm happy to see this forum and we will monitor it often. Any advice will be appreciated. Thanks
