Rear auxiliary heater

The available rear auxiliary heater is a useful feature for Cargo Van configurations where the back is kept separate from the front, such as with the Ambulance Package. It is included with rear air conditioning for non-Ambulance Package applications and available with the Ambulance Package when ordered with the Vortec 6.0L V8 SFI FlexFuel engine. It is not available with the Hotel Shuttle Package, Ambulance Package or Dedicated Compressed Natural Gas system.  The heater requires an auxiliary heat generator when ordered with the Duramax 6.6L Turbo Diesel V8 engine, and it is not available with the Ambulance Package with a diesel engine.
