I did a modification (I'll start a different thread for that), but it required cutting a hole in the side of my Montana. I thought I get some photos of exactly what is inside those wall and how they are put together. So, here it is! Notice, the walls are 1 7/8 inch thick. This is the main wall, not a wall in the slide out.
