Abstract
Abstract A load dumping vehicle including a frame, a gas turbine engine supported by the frame and a dump body pivotally connected to the frame for movement relative to the frame between a load carrying position and a dump position. Exhaust from the engine is ducted under the dump body through first and second exhaust ducts. Part of the exhaust flows into the dump body to heat the load. The ducts are connected at adjacent ends by a coupling structure which seals the juncture of the exhaust ducts when the dump body is in its load carrying and in its dump positions.
