It contains a dinette for 4 which converts to a queen sized bed. A full height kitchen counter with sink, electric cooler and lots and lots of cabinet space!
It has a water closet (uses a portable toilet to eliminate the need for a black water tank).
Dual deep cycle batteries, power inverter, A/C, fresh and grey water tanks, and even a doggy door leading out to a pet patio (because my odd little dogs will actually use a cat box filled with cedar bedding), so I do not have to worry about the puppies needing to go in the middle of the night.
The over head cabinets over the bed will contain an LCD screen and DVD player as well as a standard car stereo (actually the car stereo is an all in one unit which also plays dvds) and plenty of storage space. There will also be two small cabin lights so that one person can read without distrubing the other. The pull-out drawers will be more narrow than shown in the drawing to make room for the wheel wells.
Here are the drawings:
