A truck mounted payload loading and unloading apparatus comprising a tilting bed supported over a frame assembly. The aft portion of the tilting bed being connected to the frame assembly by a link member disposed therebetween. The link member having a first end pivotally connected to the frame assembly at a link pivot joint. Wherein the link member is pivotable about the link pivot joint. The link member having a second end pivotally connected to the tilting bed at a bed pivot joint wherein the tilting bed pivot joints about the bed pivot joint about a substantially horizontal aft pivot axis. The tilting bed being pivoted by a first actuator operatively disposed between the frame and the tilting bed to drivingly engage the tilting bed and tilt the same about the bed pivot joint responsive to actuation of the first actuator. The bed pivot joint being movable in a direction parallel to the longitudinal axis of the vehicle and downward responsive to actuation of a second actuator operatively disposed between the frame and the link member. The movement of the first and second actuator being synchronized so that the same move in a predetermined manner wherein the aft end of the tilting bed shifts rearward and .downward responsive to actuation of the actuators.
