Third is something I would say would be useful in my scoutmaster position. I like the boxy look of the offroad tears, and I'm a Jeep nut too. This kind of reminds me of the Weekender... and for now I'm going with the Overnighter, since that's what scouts do.
The lower galley wall is 1' from the rear, leaving 7' of legroom. I can probably get by with 6'6" of legroom, and that would allow a cooler to be placed on the galley floor.
Not sure yet how I'm going to do the rear wall, but it's not going to be connected to the hatch.
The tongue box can be accessible from the inside since there's no room for a front cabinet. Perhaps divided upper and lower - a shelf for the inside and a battery box and electrical accessible from the outside.
It's a work in progress... and as you can see I'm starting to get a handle on Sketchup.
