I started drawing layouts on graph paper then switched to Draw on google drive because I made changes so often. I went through many iterations before I ended up with this layout (and later installed bunks, which can be removed, that are not shown on this diagram):
Edit: In 2024, I removed the stove/oven, and replaced with a collapsible shelf and a single burner propane stove. That gave me enough length on the driver side, as well as the passenger side to build north/south twin beds along the walls.
