"IMO, the Montana is a non-starter, the bathroom can not be reached without deploying the slide (or crawling over the bed). I also would not care for a rig that we couldn't eat on the road, with the kitchen slides in."
The Montana 3900FB has a powder room as soon as you walk in the entry door. Both the powder room and the refrigerator can be accessed without deploying the slides. As far as the dinette goes, both units have them in the curb slide. So that's a wash. I still believe that the Arctic Fox is better built. i just can"t sway my wife away from the Montana floor plan.
