Ernie,
I know you've already selected your specific model types, but I'd like to ask anyway, have you considered the 5er Front Living room models.
We have a Montana High Country with a front living room, and we absolutely love this arrangement. The bed room is in the back, living room above the hitch over-hang. There's no walls between the living room area and the kitchen area. The heat difference between the upper level and the lower level is not noticeable at all, and there is ample room in the living room area for 6 people to sit comfortable.
Ours is the Montana High Country 375FL, which has the second door on the back side of the trailer. There is no island in the kitchen, which makes everything accessible when all the slides are in.
Just asking, if you haven't considered a front living model, you might want to check them out before making a final decision.
