While all this room to stretch out is nice, it's only the beginning. Topping the back seat's list of gee-whiz features are the first-ever reclining rear seats in a full-size pickup. Add huge, wide-opening rear doors and a 60/40 split-folding rear seat that offers more than seven cubic feet of storage with the seat up and more than 70 cubic feet with both sides folded down, and you have an interior that's as practical as it is comfortable.

The cabin's other desirable qualities include reduced noise levels, power-adjustable pedals, optional side curtain airbags, and an available rear-seat DVD entertainment system. Comparing the Mega Cab's interior with those of other crew-cab pickups is like comparing an airplane's first-class cabin with the cheap seats in coach.

On the Road
Slide behind the Mega Cab's steering wheel and you'll find the Hemi and Cummins engines provide impressive acceleration and remarkably quiet operation. While the Hemi may be the popular way to go (nearly half of all Ram buyers choose it), the Cummins's superior fuel economy, great gobs of torque, and excellent overall driveability make it our hands-down engine of choice.

On the road, both the two- and four-wheel-drive Mega Cabs handle surprisingly well. The ride quality also was quite good on 2500 models, but the 3500's heavy-duty underpinnings cause a slightly rougher ride.

Steering was nicely weighted and offered a precise feel that made the truck feel smaller than the 20-foot-long beast it is. When it comes time to get on the brakes, massive 13.9-inch antilock discs at all four corners produce sure stops with minimal fuss.

A Successful Trade-Off
Considering more folks are buying four-door pickups for personal use than ever, we think the Mega Cab's bed/cab trade-off succeeds brilliantly. Ultimately, we have to agree that, in the case of pickups at least, if a little space is good, a lot really is better.
