I was hoping that someone would take a minute and educate me on the 4x4 operation of the 2500HD 4x4 trucks.

When the truck is operated in 4x4 mode does the front differential lock or does it operate in an open type of mode?

I guess I am just wondering how the tires are going to pull in snow/ice or if the truck gets caught in a gully with one or more tires off of the ground.

Thoughts/Ideas?

Thanks,
