The present invention is directed to an auxiliary power unit for use with a vehicle, typically a truck. The power unit uses an air-cooled generator and associate d auxiliary engine to supply power and air regulation requirements to the truck on demand. The air - cooled auxiliary engine is employed with an electrical generator and a compressor to provide the auxiliary power unit. The unit is self contained in that it is not interconnected with the vehicle liquid coolant systems. A remote control module directs the operation of the power unit to supply heating and air conditioning to the vehicle interior by a sleeper unit. The sleeper unit provides a heating source and a coolant source that are powered by the power unit. A housing fo r the power unit is designed to assist in cooling and maintenance of the power unit. A series of air inlets are used to direct cooling air from the surrounding air over the generator, engine, and a condenser, so that operating temperatures of the power unit van be maintained within acceptable parameters. The housing also has an access cover that allows the contained power unit to be removed from the housing on a series of guides or channels, thereby facilitating the serviceability of the unit.
