Abstract: Optionally expandable passenger seating is provided in a second compartment of a vehicle body including a first compartment and a second compartment rearwardly adjacent the first compartment, through use of a passenger seating cushion attached to an interior surface of a rear wallgate, of the first compartment, optionally separating the first and second compartments from one another. The rear wallgate is attached at a lower edge thereof for pivoting movement from a vertical position, whereat the rear wallgate at least partially separates the first compartment from the second compartment with the interior surface of the wallgate facing into the first compartment, to a horizontal position, whereat the rear wall gate extends into the second compartment with the interior surface of the rear wallgate facing generally upward, thereby allowing a passenger to sit on the cushion when the rear wall gate is in the horizontal position.
