Selling our M813A1 6×6, all wheel drive, 5 Ton tanker truck. The truck was originally built by Kaiser then refurbished by AM General at a later date.

This vehicle was used by the Forest Service as a water tanker for remote fires. We acquired the vehicle last year and went through the mechanicals, changed all of the fluids, repaired the wiper air lines and replaced the blades, horn, axle seals, temperature sending unit, lights, heater blower motor and emergency brake. We also added front and rear LED light bars, locking door handles, a new PTO, reworked the battery box, installed new rubber cord for the canvas top and rebuilt the fuel shut off valve and many other pieces.

Over $17,000 was spent on upgrades on the vehicle after acquiring it, with the primary intention of using the vehicle on our oil & gas leases to move petroleum condensate and other liquids.

While the original tank itself is carbon steel, we installed an extensive, stainless steel plumbing system underneath the truck which is run by a new model 7409588 PTO running a Corken Coro-Vane Z3200HGAPGE LPG Truck Transfer Pump with a Corken ZV200 bypass valve. The pump will put out 110gpm at 800RPM. The system has a 3″ stainless suction line and a 2″ stainless discharge line. The discharged fluids can be run either through 2″ diameter hoses with camlok fittings or through an onboard inch and a half hose reel. You just engage the PTO from the cab, set the throttle and the fluid will circulate back to the tank until one of the discharge valves is open. There are Y strainers on both the 2″ and 3″ lines to catch anything coming to the pump or to catch any rust or paint that may come out of the tank. The top of the tank has a large pressure relief cap.

Also on the system are mounted multiple fire extinguishers and a retractable air hose reel which can be used to inflate any of the 6 wheels while in the field or it can be used to blow out the lines. We have drain valves throughout the plumbing system so that it can be purged and put away dry to eliminate any freezing issues.

The vehicle also has a marine deep fording kit installed with a special air box, exhaust and cab controls.

The engine in the truck is the 855cu in Cummins NHC250 straight 6 diesel which is known as the “million mile engine”. These were used in long haul trucks for years. The odometer shows under 32,000 miles but it is not known if that is accurate.

This would be a great truck to put back into service as an offroad fire truck. The tank is not DOT certified so the truck cannot be used to transport hazardous liquids on public roads. The truck is geared very low so top speed is about 65mph.

The axles on the truck are the very desirable Rockwell Standard, single speed, units. All 6 wheels are engage all the time.

I also have a set of larger wheels and tires available for this truck which I am selling in a separate ad. They are Michelin XML 395/85R20 46″ tires mounted on 5 ton MRAP rims. I have 7 of these. Some are brand new, some are slightly used., all of the tires on the truck and the spare set can have the tread re-cut.

Call or text if you have any questions or would like to see the vehicle. In the photo with the water going through the hose, the engine is at idle. The system puts out quite a bit of water when the RPM’s are increased.

Our company is based in Texas. We have a clean, Blue Texas title for this vehicle. It can be shipped.

There are 2 issues with the truck. When the engine is running at high RPM, we are getting some oil slung from the front cover near the fuel pump. It probably needs a gasket but since we drive this off road at low speed, it hasn’t been an issue. We also have 2 wheel with slow air leaks through the rim. I have new O-rings for the rims but haven’t installed them yet.
