We use this air compressor with the 23D and Mercedes. We have a special two pole twist-lok plug on the compressor and a #10 wire 25' two conductor extension cord that can plug into a dedicated outlet in the back of the refrigerator compartment so the unit can air both the trailer tires as well as the tow vehicle tires.
