This 1983 AM General M923A is powered by an 855ci inline-six Cummins diesel engine coupled to an Allison 5-speed automatic transmission with dual-range. This truck was used for military service from 1983-2010 it was purchased from a government surplus auction by a dealer and converted for civilian use. Originally a 6×6, the frame was shortened and one drive axle was removed to create a 5-ton 4×4. The paint and interior were refreshed, all lighting was converted to LEDs, and a tow receiver was installed. It has been owned by the seller for five years and has covered 2k miles during their ownership. This AM General is sold with a factory hard top and a clean Washington title in the seller’s name.

The truck has been repainted once in the original Desert Tan and the seller mentions that there is minor corrosion on some hardware and fasteners. The canvas convertible top appears to be in good condition and a factory hard top is included but has never been fitted. A spare tire is also included which currently sits in the bed but should be mounted on the hood. The bed has folding side panels that can be opened or removed to create a flat bed. All lighting has been converted to LEDs.

The no-frills interior has recovered seats with conventional seat belts. Features include ABS and power steering. The electrical system is 24 volts however when recommissioned a 24 to 12 volt converter was added for a trailer setup. A conventional keyed ignition was recently installed and all controls and gauges are reported to work well.

The Cummins 855ci diesel is rated at 240hp and 685 ft-lbs of torque. The Allison dual range 5-speed automatic transmission has modified gears that allow it to drive at highway speeds. The 4 wheel drive system can be engaged on the fly. The seller reports that it has been rebuilt several times by the military and no repairs have been necessary during his five years of ownership. The batteries were recently replaced and the oil was changed one year ago.

During the conversion for civilian use, the frame was shortened and one rear axle was removed. The Rockwell axles feature air brakes with ABS. A tow hitch receiver was added during the recommissioning and the seller reports that it will tow 15,000 pounds. The seller notes that the vehicle can also be viewed at Group 2 Motorsports where it is currently stored, and that a road test and inspection can be arranged at Group 2 in Seattle as well.
