Welcome to the forum. I think you will find that the Montanas have the same basic construction for all models. The best floorplan is the one that fits your lifestyle. We had a 3400 but moved to a side aisle (365 Big Sky) after the grandkids started getting a little older for the separate bathroom. I believe you will find the Montanas well built and thought out. They aren't perfect, but many of us have had two or more Montanas. We have found the Montana brand to really listen to their customers and make changes based on input. And the MOC is a great group. Good luck on your decision.
