M931A2 6x6 5-ton made by BMY. $21,000

Scroll down for photos and 6x6 parts for sale.


Titled as 1990 and registered with Historic plates.

The military sent this truck through “reset” whereas the truck was fully disassembled and each of its components sent back to the manufacture and rebuilt. It is considered “zero timed”. The frame was sandblasted and the rebuilt components installed. The doors and glass are new.

The engine is a turbocharged Cummins 8.3L straight-six.

The transmission is a 5 speed Allison automatic.

The truck has air brakes with a “sneezer”. It appears to be a CDL is not required if not used commercially or as a combination (using the 5th wheel). The code seems clear on this. I’m not an authority here.

The truck came equipped with the central tire inflation system. These were very unreliable. All parts are there and it worked when tried.

The truck is equipped with ABS (Anti-lock brakes). This is a big deal on a bob-tail tractor. Nice.

The tires are 14.00R20’s with lots of treads.

The truck has military rear splash guards on a custom bracket. Looks great.

Sun has damaged both seats. Mainly passenger seat.

The rest of the truck is very nice. No other known squawks.

After reset, it spent its days sitting in a lot until the government sold it at auction 4 years ago. Looking at the 5th wheel, it hasn’t been used more than a couple of times.

Removing the 5th wheel plate provides a platform for making your back-end. Flatbed? Pickup? Camper? Haul your HMMWV? In and out of oilfield leases? What a great 6x6 Cummins platform for less money than a 4x4 diesel pickup. Cool.

I’ve put well over 1,500 miles on the truck. The short wheelbase is great for maneuvering and we routinely park it in standard parking slots at hotels and restaurants. Try that with an M923! Fun and usable.
