A vehicle mounted loading and unloading apparatus is provided which has a stationary mounting rack removably attachable to a roof of a vehicle and a top rack that includes a container for storing cargo, such as bales of hay. An adjustment mechanism is provided to move the top rack relative to the mounting rack from a transporting position to a loading/unloading position in which the top rack is lowered behind the vehicle to facilitate loading cargo. A movable shelf may be provided on the top rack for assisting with loading and unloading cargo. The shelf is slidable between a rear end of the top rack and a front end of the top rack for placing the cargo.

A roof-top rail system has a fixed frame mountable to the roof of a vehicle and a moveable frame mounted to the fixed frame. Bearings attached to the frames may engage channels formed in rails of the other frame in a manner such that as the moveable frame slides backward relative to the fixed frame, the moveable frame extends from the back side of the fixed frame. Simultaneously, a back end of the moveable frame rotates down as it extends from the fixed frame to improve access to cargo securing features of the moveable frame.

A moving mechanism is provided to move the top rack relative to the mounting rack from a transporting position to a loading/unloading position in which the top rack is lowered behind the vehicle to facilitate loading cargo. The top rack is guided from the transporting position to a loading/unloading position by a track structure extending from the mounting rack, which cooperates with a bearing structure fixed to sides of the top rack. A movable shelf may be provided on the top rack for assisting with loading and unloading cargo. The shelf is slidable between a rear end of the top rack and a front end of the top rack for placing the cargo.

A rollback dump truck having a chassis, a support frame, a bed frame, and a latching extension. The chassis further having at least one rear axle laterally extending between two sides and a pivotal axis parallel and rearward thereof. The subframe assembly is positioned above and supported by the chassis and is operatively connected thereto at a hinge point aligned with the pivotal axis. The subframe assembly may pivot about the hinge point away from the chassis to positions that include a dump position and a load position. Additionally, the bed frame may slide relative to the support frame in the load position while the load angle is held constant by the latching extension.
