Abstract: The present invention is in the form of a body (111) adapted to be fitted to a truck having at least two axles. The body is capable of tipping once fitted to the truck. The body comprises two side surfaces (13) interconnected by a longitudinal surface (21) to keep the side surfaces in spaced apart relation. The longitudinal surface and the side surface define a cavity (30) for receiving a payload. The longitudinal surface is configured such that the payload is self-centering as the body is loaded, such that in operation the distribution of load on each of the at least two axles remain substantially the same between a first payload having a first volume and a second payload having a second volume, neither payload resulting in the gross vehicle weight limit being exceeded.
