Below are photos of the dinette setup in out 89 Ford RB.
The dinette setup up for normal seating. There is 14" between the seats. Four sets of seat belts are stored in the cabinets below, two on each side. The heater and storage space is on the passenger side and the fuse panel, other electronics and storage is on the driver side under the seat.
The dinette setup for eating. The table is 18x38. This is a little tight by the time you get plates, tableware, glasses, and serving dishes on it but great when it is cold outside. The heater is right under the seat on the passenger side so your feet stay nice and warm.
Here is the unit setup for sleeping. The dinette folds out to a bed that is 48" wide and about 70" long. I just fit lengthwise if I am laying on my back. When Ann and I are both in it there is enough room to sleep apart so as we do not disturb each other.
