A vehicle for supporting cargo includes an upper and lower frame for supporting cargo at an upper and lower level, respectively. The vehicle includes forward and rear support towers. The forward support tower is located in the forward portion of the vehicle, fixed to the lower frame, and is pivotally connected to and supports the forward portion of the upper frame. The rear support tower is pivotally connected to and supports the rear portion of the upper frame, and is pivotally connected to and supported by the rear portion of the lower frame. The rear portion of the upper frame supported by the rear support tower can be longitudinally displaced relative to the rear support tower, and the upper frame can be pivoted, about the pivotal support on the forward support tower, to move the upper frame between an upright position and a loading position. In the upright position, the upper frame is supported in an elevated substantially horizontal alignment by the forward support tower and the rearward support tower. In the loading position, the upper frame is inclined with the rearward portion thereof extending downwardly to facilitate loading and unloading of the upper frame.
