We are on our third Montana. A 2008 3400 was first, and it was a good unit with a few minor problems. Our second was a 2011 3400, better unit, with a couple of minor problems. Our third (and current) one is a 2014 3725, and it is the best one yet. Better insulation, better features, overall a better unit than the previous two. And, after a year of use, zero problems, at least so far. I totally agree that having a good dealer behind you makes all the difference. Curtis trailer is our dealer, and they have been absolutely fantastic to work with. I also agree that ANY manufacturer is going to have some problems. Look at all the recalls on cars and trucks! Yes, there are fivers that you could spend close to $200,000 on, but are they better?
