Despite their bulk, these Mega Cabs steer, ride, handle and brake at least as well as competitive long-wheelbase heavy-duty pickups. The HEMI V8 delivers its 375 pound-feet of peak torque...
at 4200 rpm and its 345 maximum horsepower at 5400 rpm, and the five-speed automatic provides smooth power at any reasonable speed.
The Cummins Turbo Diesel, by contrast, unleashes its monster 610 pound-feet of max torque at just 1600 rpm and its 325 peak horsepower at 2900 rpm. This is great for launching with heavy loads and for off-road creeping, but on-road if you start in first gear, you'll need to shift to second almost immediately and to third before reaching 20 miles per hour. The available four-speed automatic upshifts smoothly and quickly enough to mask this musclebound diesel's narrow torque band.
