We bought a Montana High Country in 2012 and have been very disappointed in the interior quality. Cabinet door panels fell out, blind tensions were incorrect and had to be adjusted by me. The list goes on and on.
And then to aggravate the situation, we parked the unit for 2 1/2 months after we bought it (not camping situation after all) and then when we took it in to get things fixed, the dealer told us that Keystone only reimbursed them for fit and finish problems for 90 days and they really didn't want to fix those problems at their cost.
We were told by friends not to get a Montana because the workmanship was second rate. I wished we would have listened.
