Disclosed is a system to assist hauling and loading of cargo above a passenger truck. The system has a forward frame and a rearward frame that are pivotally attached to the cargo area of the passenger truck. The frames tilt between an upright stowage position and a downward loading position. The frames are connected by a mechanical-advantage member to tilt the rearward frame faster than the forward frame when moving between the loading and stowage positions. Additionally, a spring, piston or other force facilitator device can be used to gain further mechanical advantage.
