A truck includes an alternator having a direct current electrical power output. The truck also includes an inverter having an alternating current electrical power output, and a battery. The truck further includes a day cab forming an interior space and a climate control unit for conditioning the interior space of the day cab. The climate control unit has a conditioning capacity rating that is not greater than 7,000 British thermal units per hour (Btu/hr). The climate control unit is adapted to be powered by an alternating current electrical source. The climate control unit is powered by the alternator through the inverter when an engine of the truck engine is running and powered by the battery through the inverter when the engine is not running.
