A box truck for supplying sufficient electrical power and compressed air flow to enable spray foam contractors to use specialized equipment to foam insulate buildings. Such a truck has the necessary generator and air compressor systems mounted within the chassis of the vehicle and said systems do not take up valuable cargo space within the truck box, while utilizing components present in normal box truck designs to assist in their operation. The generator system is hydraulically powered and utilizes a PTO (Power Take-Off) mechanism to use power from the truck power train to drive the hydraulic system. The air compressor is a screw type compression system and is belt driven off the truck engine.
