Let's see your Ford or GM do this
 

At the beginning you can see both axles are in the mud;

That truck isn't as stuck as it looks. His left side drives are up on solid ground. Front axle is the driving axle. Once the power devider is locked in, power will go to the rear axle that doesn't slip also.

You think those Army boys were pulling a fast one? The way I see it the rig doesn't get on solid ground without the Cummins.

So you dont think a Ford or Chevy diesel is capable of spinning tires in 4wd anchored to a semi? The suprising part is that the POS transmission in the Dodge didnt let go. Must have been a 6-speed.

Here you go

Drop my dually in low gear and let the clutch out and I'd have ripped that thing right out.....

It's more about traction.....

That Catmando is just a trouble maker! lol:evilb:

And a non stop Cummins commercial. :party-smiley-004:

Cat I pulled out a truck like that with a hydrolic boat trailer and a 48 foot cruiser attached to it up a 45 degree ramp and barely had to touch my gas pedle.

ROFL :bsflag: :D
