We toured both plants (Heartland and Montana)and felt both had good quality features. We chose the Montana because of the floorplan and the design on the front framework behind the front cap} The Montana had all aluminum welded and the heartland had 2x2 lumber held together with screws. the particular unit we saw did not look like it would make it to the parking lot without falling apart. This may have been repaired before the front cap was installed. We'll never know and I'm not meaning to say Heartland is bad based one that one item. I felt they were both good units. Montana's floor plan just fit us better.
