2018 Promaster 3500 159 Extended, floor to rear doors is 160 inches in the center, a little less along the sides due to the rear and front corners
The floor plan is such that the 3/4 full bed runs from side to side about 16 inches in front of the back doors, and ends right at the front of the wheel wells, leaving plenty of room to extend the Smartbed Evolution R and still have about a foot between the two, it is a fairly large van! All the electrical and water systems are under the bed, and the permanent shower is in front of the bed on the side opposite the smartbed.
