I don't see the width specs any where about the Alpine that says it is 6" wider than the Montana. I like the Alpine 3701 FL model, since it has a front window like we have on the 3820FK Montana. I only see Alpine mention way down in the features "Big Body width with next generation construction"? If it is 6 inches wider, do they compromise on the wall thickness, or do they make the wall thickness thicker for more insulation, or is it the same wall thickness, and you actually get 6 more inches of space in the interior?
