Big Truck, Big Engines
Like all Ram pickups, the Mega Cab is available in three distinct models: half-ton 1500, 3/4-ton 2500, and one-ton 3500. Buyers also can choose from two different trim levels, including the upscale SLT and top-line Laramie.

With this truck, there are two excellent engine choices. The 5.7-liter Hemi V-8, which puts out an impressive 345 horsepower and 375 pound-feet of torque, is standard on 1500 and 2500 models. The 5.9-liter turbodiesel Cummins I-6, which cranks out 325 horsepower and a stump-pulling 610 pound-feet of torque, is optional on the 2500 and standard on the 3500.

A five-speed automatic is the only transmission offered with the Hemi, while the Cummins comes mated to either a new six-speed manual gearbox or an optional four-speed automatic transmission. Both powertrains can be had with rear drive or part-time four-wheel drive, which comes with a low-range transfer case.

Properly equipped, the Mega Cab 1500 can tow a respectable 7750 pounds. If you've got truly big toys to haul, look to the 2500, which can tow up to 12,900 pounds, or the 3500, which can handle trailers weighing up to 15,800 pounds.

First-Class Interior
Up front, the Mega Cab has all the same strong points as other Ram models, including clean styling, a functional layout, and decent leg- and headroom, even for big-and-tall types. While the front seat is good, the second row is where this new model really shines.

The extra inches grafted onto the cabin make the Mega Cab's rear seat downright limo-like. There's plenty of room for three adults across and legroom so abundant it puts the GM and Ford crew cabs to shame.
