Does any truck manufacturer make a 4x4 chassis cab powered with a CAT C7 ?

GMC almost has one with their 4500 5500 TopKicks - but no CAT power until you get to the 6500.

Freightliner - nice trucks - but no 4x4 !

Guess they all figure 4x4 is for off-road, and nobody is gonna take a bigger truck offroad - right?

But what I figure is that it's for Snow and Muddy Dirt roads, and Sand ! Sometimes I pull off somewhere where I wish I hadn't too.

I couldn't be the only one that thinks this way - or could I ?

Seems that I was in error -
Freightliner does make a 4x4 SportChassis Cab....with a CAT C7.
Just isn't mentioned on their website.

International has the I think it's called RTX with 4x4. It's full time 4x4. They were a big thing at SEMA a couple years ago. I think 3 years of $3 diesel has slowed sales down. Didn't see many Internationals or Sport Chassis M2's at SEMA this year.
