To chime in we are very pleased with our Montana 3400. Our dealer adds to that with good support. Not to avoid criticism of a good product, you may also want to look at
http://www.rv.net/forum/, another rv forum site that has more universal owners that could give you another side to Montanas and other brands from their perspective. I believe that with over 8000 MOC owners here most are generally or greatly pleased overall with their Montana choices. Of many I am one. Good Luck on your choice.
