A truck body that efficiently hauls homogeneous and cohesive materials that typically coagulate and adhere together in one consolidated mass. The adhesion of this consolidated mass to the surface of the truck body is minimized and the build up of “carryback” is effectively prevented during haul cycles. Hauled amalgamated materials are dumped from the truck body such that the amalgamation breaks up and is safely dumped. One typical material that displays such a coagulated conglomerate massing is “oil sands” from which oil is extracted. A non-stick surface is provided on the truck body to overcome the natural adhesiveness displayed by this material and, when being dumped from a truck body, provides a means to assist in releasing the material from the truck body without leaving significant “carryback” that tends to build up over haul cycles. Plus, the body design encourages the material to break up as it is dumped.
