The Mega Cab offers a more spacious interior by extending the cab some 20 inches compared to the standard 4-door crew cab model. The Mega Cab is based on the 2500 heavy duty series long bed frame only with the shorter 6' 3" bed installed. Mega Cab is offered in 1500, 2500, 3500 models in 4x2 and 4x4 configurations. Powertrain options are limited to 5.7L HEMI V-8 and a Cummins turbo-diesel with over 600 lb-ft of torque. Trucks usually have very cramped rear seats, but the Mega Cab features rear seat leg room in excess of 44 inches making it more spacious than that of a standard wheelbase Town Car or Cadillac DeVille. Despite the civility of its interior, the Mega Cab is still a long truck. It seems destined for improving the life of those that pull trailers on the highway.

What Changed:

A 6.7L Cummins turbo diesel engine rated at 350 hp and 650 lb-ft of torque will replace the optional 5.9L diesel. A choice of six-speed manual and six-speed automatic transmissions will be offered with the new engine.
