Considering 2007 Montana 3400RL - please help!

Don't even consider it. We owned a 2006 3400RL that gave us nothing but grief for 9 Years. All the decals peeled off which compared to everything else was a minor issue . We sold it in the summer of 2015 and were very happy to get 19,999 for it. Keystone/Montana 5th wheels have all kinds of quality issues which are too numerous to mention here. Don't touch it.
