He is a sample of what can be done with a rear air conditioner. This bus had a large luggage compartment that was not needed any more. We reinforced the ceiling in the new location and welding the A/C in the new spot. The power wires and the freon lines were extended as well. These units can also be completely removed for someone converting a bus to something such as an RV that wants a more traditional A/C that does not run off of the engine.
