Available in 1500-, 2500-, or 3500-Series trim dressed up in SLT or Laramie garb and either 2WD or 4WD, the 2006 Dodge Ram Mega Cab is available with one of two engines. The Ram 1500 Mega Cab is only offered with a 5.7-liter, 345-horsepower Hemi V8 making 375 lb.-ft. of torque at 4,200 rpm. The Hemi is also standard on the Ram 2500 Mega Cab, and an industrial-strength, 5.9-liter, 310-horsepower Cummins turbodiesel engine with 610 lb.-ft. of earth-shaking torque peaking at 1,600 rpm is optional. The Ram 3500 Mega Cab is equipped with the turbodiesel engine right out of the chute, and when properly equipped, the 3500 Mega Cab can tote 2,840 pounds of payload and tow a trailer weighing 15,800 pounds. The Hemi is hooked to a five-speed automatic, while the Cummins comes with a six-speed manual or a four-speed automatic. In addition to impressive powertrains, Dodge claims that the Mega Cab is equipped with the largest brakes in the segment, and they come with ABS and electronic brake-force distribution.

Standard equipment includes the usual litany of power accessories plus 17-inch wheels and tires, a 60/40 split-fold rear bench seat that reclines and slides, and storage bins behind the back seat that measure 7.6 cubic feet of volume. With the rear seat folded, the Ram Mega Cab swallows 71 cubic feet of stuff, better than most compact SUVs for weather-protected cargo space. Options include a 384-watt Infinity sound system with Ceramic Metal Matrix speakers, Sirius satellite radio, a navigation system, UConnect Bluetooth wireless communications, and a rear seat DVD entertainment system with game ports and a 6.5-inch wide screen. Side-curtain airbags, power adjustable pedals, a power sunroof, and heated front seats are also available.
