Abstract: A vehicle for use with a plurality of interchangeable truck beds, i.e., functional units. The vehicle includes a chassis and an engine and cab mounted on the chassis. The chassis extends rearwardly from the cab from a first location to a second location at the rear end of the chassis. A first mounting interface is disposed near the first location and a second mounting interface is disposed near the second location. The mounting interfaces each include a substantially horizontal support surface and a guide member. The interchangeable truck beds include mounting structures that are secured to the mounting interfaces on the chassis. The guide members on the mounting interfaces are used to properly position the mounting structures on the chassis. The truck bed may be a dump truck bed that includes a hydraulic ram having a base structure that is secured to the first mounting interface and a hinge structure that is secured to the second mounting interface.
