A truck includes an alternator having a direct current electrical power output. The truck also includes a combined inverter and charger unit having an alternating current electrical power output, a house battery and a starting battery. The combined inverter and charger unit is configured to charge the house battery and the starting 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 is adapted to be powered by an alternating current electrical source. The climate control unit is powered by the alternator through the combined inverter and charger unit when an engine of the truck engine is running, and is powered by the house battery or the starting through the combined inverter and charger unit when the engine is not running.

The truck as set forth in claim 1, wherein the truck is a tractor adapted for pulling a semitrailer. 3. The truck as set forth in claim 1, wherein the truck further includes a battery isolator for preventing a flow of current from the starting battery to the house battery and thereby prevents discharge of the starting battery when the engine is not running, while allowing the alternator to charge the house battery when the engine is running. 4. The truck as set forth in claim 1, wherein the starting battery or the house battery is an absorbed glass mat battery. 5. The truck as set forth in claim 4, further comprising an additional absorbed glass mat battery. 6. The truck as set forth in claim 5, wherein the starting battery and the house battery have Ampere-hour ratings that are not greater than 75 Ampere-hours. 7. The truck as set forth in claim 5, wherein a conditioning capacity rating of the climate control unit is a cooling capacity rating that is within a range of about 7,000 British thermal units per hour (Btu/hr) to about 10,000 Btu/hr. 8. A truck, comprising: an engine;an alternator driven by the engine;a starter motor for starting the engine;a combined inverter and charger unit having an alternating current electrical power output;a day cab forming an interior space;a climate control unit for conditioning the interior space of the day cab, wherein the climate control unit is adapted to be powered by an alternating current electrical source, and wherein the climate control unit is powered by the alternator through the combined inverter and charger unit when the engine is running; anda battery for supplying electrical energy to the starter motor, wherein the combined inverter and charger unit is configured to charge the battery, wherein said battery supplies electrical energy to the climate control unit through the combined inverter and charger unit to power the climate control unit when the engine is not running, and wherein the combined inverter and charger unit is configured to be connected to an alternating current shore power source having an alternating current voltage level to thereby supply the climate control unit with electrical power from the alternating current shore power source and also to charge the battery with a charging voltage when connected to the alternating current shore power source, wherein the electrical power supplied to the climate control unit by the combined inverter and charger unit when connected to the alternating current shore power source is at a transformed alternating current voltage level transformed by the combined inverter and charger unit from the alternating current voltage level. 9. The truck as set forth in claim 8, further comprising an additional battery, wherein the combined inverter and charger unit charges the battery and the additional battery, and the battery and said additional battery form a battery bank for supplying electrical energy to the climate control unit through the combined inverter and charger unit to power the climate control unit when the engine is not running. 10. The truck as set forth in claim 9, wherein the battery and said additional battery have Ampere-hour ratings that are not greater than 75 Ampere-hours. 11. The truck as set forth in claim 9, wherein the battery and said additional battery are absorbed glass mat batteries. 12. The truck as set forth in claim 9, wherein the climate control unit has a cooling capacity rating that is not greater than about 7,000 British thermal units per hour (Btu/hr). 13. A method of modifying a truck, comprising: providing the truck, the truck including:an alternator having a direct current electrical power output;a house battery;a starting battery;a day cab forming an interior space; anda heating system for heating the interior space of the day cab;installing a combined inverter and charger unit on the truck, the combined inverter and charger unit having an alternating current electrical power output; andinstalling an auxiliary HVAC unit on the truck, wherein the auxiliary HVAC unit is adapted to be powered by an alternating current electrical source; andwherein the auxiliary HVAC unit is powered by the house battery or the starting battery through the combined inverter and charger unit when an engine of the truck is not running, and wherein the combined inverter and charger unit is configured to be connected to an alternating current shore power source having an alternating current voltage level to thereby supply the auxiliary HVAC unit with electrical power from the alternating current shore power source and also to charge both the house battery and the starting battery with a charging voltage, wherein the electrical power supplied to the auxiliary HVAC unit by the combined inverter and charger unit when connected to the alternating current shore power source is either at the alternating current voltage level of the alternating current shore power source or at a transformed alternating current voltage level transformed by the combined inverter and charger unit from the alternating current voltage level. 14. The method as set forth in claim 13, further comprising installing a battery isolator for preventing a flow of current from the starting battery to the house battery and thereby preventing discharge of the starting battery when the engine is not running, while allowing the alternator to charge the house battery when the engine is running. 15.
