Our 2011 Montana was flawless. Our 2015 had its problems and a noticeable drop in quality. Once we got the bugs out it has been trouble free. Camping World Spartanburg really took care of our concerns. Sometimes the servicing dealer can make the total difference in repairs, Just stick with it and be firm but not disrespectful. remember you don't want to make the people mad at you that you are trying to get to help you.
