As we continue with the installation of cabinetry, the space gets even smaller. Maybe because I'm 6'4" and 250 pounds, I just have a hard time seeing two people camping in this tight of a space although the owners are very compatible so it will work out. We installed the fresh water tank and cabinetry that encloses it along with the seating/storage cabinet on the passenger side. That slot is a site window for checking the water level in the tank. Seat tops are in and now its time to wire, plumb and run propane lines.
