The deuce's engine torque is not much to brag about (300 lb-ft). I'm not so sure that the two axle FMTV M1078A1 couldn't out pull the deuce. It's cat engine has a torque of over 800. Don't know the gear ratios, though.

Do the same for the Loadstar and you'll know who will win. Loadstar torque, gearing and tire size should do it.

These are the numbers: 300 x 5.02 x 2 x 6.72 x 0.85(fudge factor) ______________________________ = 10,120 lb 1.7 (tire radius) The engine torque is about 300 lb-ft.

Yes, only then will the engine torque be used fully. And that's what determines the outcome.

Okay, the drawbar pull is determined by the engine torque multiplied by the gear ratio multiplied by fudge factors related to efficiency of the system etc. The weight of the vehicle doesn't enter into the picture EXCEPT for the fact that it will keep the tires from spinning. Smaller tires will...

All else being equal, I have to say that the truck with the lowest gear ratio multiplied by the engine torque will win. And don't spin the wheels.
