A device provides utilities, including both mechanical and electrical sources of power, and various power tools, from a self-contained and independently operable compact unit configured for transportation to, and use in, various field applications. An internal combustion engine (ICE) mechanically drives an electric generator, an air compressor and a water pump. In turn, the electrical generator provides electrical power to an arc welder, a plasma torch cutter, an electric pressure washer, a light plant for providing illumination in the vicinity of the unit, and to outlets from which various external electrically powered devices may be powered. The air compressor may, in turn, supply compressed air to the plasma torch cutter and to both regulated and unregulated outlets for powering various external connected devices. Additionally, a hydraulic pump may be attached to and powered directly by the ICE. The various components of the device are housed within a rectangular box-like framework of a size and structural strength as to make the unit suitable for carriage in the bed of a standard-sized pick-up truck, and lifting with the hook of a crane or the like. A further aspect of the invention concerns a novel trailer configuration for towing the unit behind a motor vehicle.
