I'm glad you love the Montana, we have one too and absolutely love it! I now joke that if the house went up in flames to save the tent!
What won us over on it was that with the slopping walls we could still fit 2 sets of bunks in one room. We take the other room with our King size blow up mattress and the middle room stores our stuff or is a playroom on rainy days.
I also think the awning is fantastic and i love how you can open the whole tent up to get a breeze through.
