A wheeled service vehicle for manhole operation adopted for towing and comprising a chassis frame mounting a variety of equipment, the vehicle and equipment all being self-contained and including a prime mover with several pieces of equipment driven thereby. A housing for the vehicle is independently removable from the chassis frame without disturbing the equipment thereby making access and servicing of the equipment a simple matter. The equipment includes a generator driven by the prime mover to provide electrical power, a water pump driven by the prime mover and means for conditioning air supplied by a blower powered by the generator. Novel heat exchange means enables the air furnished by the blower to be warmed by the exhaust and coolant of the prime mover. The prime mover is fueled by bottled fuel and means are provided to warm the bottles for cold weather operation.
