We're happy Montana Mountaineer owners.
We've only had two problems - the shower surround leaked (I repaired it with a tube of caulking). The foot rest on one of the recliners was crooked (I took the chair to my dealer and Mastercraft sent a new frame. It was repaired and back home in one day). The coach has never been back to the dealer. We are happy with our purchase and would do it all over again. We may consider a 5th wheel when we go fulltime and we'll definitely consider a Montana for that purchase.
