Purchased in May, 2009 second hand from the U.S. military. This truck was stationed in Tennessee, at least that's where it was when I bought it. I plan to restore and change a few things to suit my needs. I am going to use it in my business as a heavy off road truck to pull massive loads in remote locations that may require an all wheel drive.
This is a heavy tractor that was used to transport tanks. The winches were used to pull a tank onto the trailer even if it were not running.
A few specs...

Fresh from Tennessee in May 2009
The M911 uses the whole 30' lower deck plus a little more.
I can just barely reach the Oshkosh lettering when we are on the ground.
The outside duals have been removed to transport.
The M911 is almost 10' wide with duals on.
Daryl Gushee climbing in for unloading.
The silver 92 is a mean sounding engine with the standard military exhaust.
Going for my first cruise in the monster.
Straight in the shop for major reconditioning.
When it comes out it will be a whole different animal.
No more olive drabb and a lot of more modern updates.
Update 7/9/09
Here it is stripped down to cab and chassis. Winches, Hydraulic tank and pumps, tool box, spare tire, spare tire hoist, rear deck, tires, 5th wheel, ramps, bumper, grill, grill guard, hood, brake cans, head lights, directionals, air cleaner, fuel tanks, and more all have been removed.
So far we have repaired a multitude of air leaks. Changed most of the oil carrying lines, and repaired some of the wiring.
All the fluids have been drained. New filters and fluids are making their way back into the truck as we can identify and purchase them.

The chassis and lower sheet metal has been sandblasted.
12" has been cut from the end of the frame and the eye hooks and rear crossmember are being remounted in a more suitable location for pulling civilian lowbed trailers.
Update 7/10/09

First coat of 2 part epoxy primer/sealer has been applied to the chassis.
UPDATE 8/1/09

The cab is painted (Gushee) green inside and out.
The military olive drab paint is some tough stuff. I think it is bullet proof.
A lot of hours were spent trying to smooth out the prior paint jobs. There were several coats of paint that you could compare to rhino liner but with huge runs that were almost 1/4" thick in spots.
Next time I would sandblast the entire cab.

The chassis is painted black and some 12"x30# channel iron has been bolted in as a base for the new winch mounts.
The fuel tanks and battery box have been cleaned, and sandblasted and are ready to go back on.
Update 8/6/09

Partially reassembled
Most of the paint work is done.
All fluids and filters are new.
The new tires and wheels have been installed on the steer axle. These are super single 425/65R22.5 tires. The wheels are rare but were found at accuride.
The wheels for the drive axles are custom built to dual out super singles. I will be putting them on in a couple days.
Also added is Hollands heaviest 5th wheel with a 42" slide to allow us to position for the biggest advantage on different loads

This is the new winch assembly. It is designed to unbolt and remove as a module unit and can be done in a minimal amount of time.
Shown here almost complete except the cab guard and completion of the paint.

I did a mock up fit of the winch module to make sure of all clearances.
This design allows for access to the pump and driveline through the top.
We made a bracket to direct mount the hydraulic pump to the auxiliary transmission using a Lovejoy coupler. This eliminated the 4' drive shaft and put the pump in a good position for service and hose connection.

Shown here removing the winch module.
Also notice the fender mount air cleaner has been removed and an under hood version scavenged from a I.H. parts truck has been installed in the engine compartment.
Update 8/13/09

Oshkosh M911 ready for civilian heavy haul business.

What a brute.

Final width 10'5" wide at the rear wheels.
LED tail lights
easily removed mud flaps
