We have been full timing since September 1, 2010 in 3 Montanas all bought new and none of them have had to go back to the dealer. A few very minor issues with non-Montana components all corrected by me. If in the market for another 5th wheel would make a beeline back to the same dealer for another Montana!
First one was a 2008 we part timed in then a 2012 and now the current 2018.
