Test Driver Ratings & Comments

Acceleration commentsYee haw! Nothing like a dually laying down double elevens: with the traction off, the best run was from 2,000 rpm. The trans is not quite as smooth as the Chevy's Allison, but almost. Upshifts occur at 3,200 rpm.
Braking ratingGood
Braking commentsLong-travel, spongy pedal, but nearly zero ABS pulse or sound. A slight tendency to tug left at max braking.
Handling ratingN/A
Handling commentsSlalom: With so much rear tire grip (x4), the understeer is the limiting factor here. Otherwise, this truck is remarkably stable and poised as long as you can turn the wheel quick enough and stay out of understeer. Skid Pad: This monster stays flat as a table all the way around and sacrifices the smoking front outside tire. Steering feels light for such a big vehicle.
