Used 12VDC Air Conditioner. A TRUE DC (does not run through an inverter)about equivalent to a 5000 BTU window unit, but made especially for Trucks. New, by the time this gets to the U.S., this unit was almost 4K. These are used in Europe by Truckers. Complaint - loud, but these are supposed to be top of the line. It is a split unit. I have more pics.
