RAM lineup was consistent, and the utility-vehicle maker considered that a full-size cabin was not an option if there was more stuff to carry inside. Also, it ensured a payload of up to 7390 lbs (3352 kg) plus a towing of 31210 lbs (14156 kg). Moreover, the heavy-duty hauler could fit up to six people inside the cabin plus their rifles or motorcycle riding equipment.
The RAM Mega-Cab 3500 HD featured a more extended cabin than the Crew-Cab, with an extension behind the rear doors. Depending on the trim options, the carmaker offered its biggest pickup from its stable with a chromed grille at the front, LED running lights, step-boards on the sides, and 20" chromed wheels. It could easily tow a full-size motorhome behind it, especially if fitted with a goose-neck in the bed.
Inside, it wasn't too much different than the Crew-Cab, albeit it offered more storage area behind the rear bench. The carmaker installed a big, 8.1" touch-screen on the center stack for the infotainment system for the front area. Inside the instrument cluster, RAM installed two large dials for the speedometer and tachometer, a few gauges, plus a TFT display in the middle.
Under the hood, RAM installed the well-known 6.7-liter Cummins turbo-diesel engine that provided an excellent pulling power thanks to the truck-like 1220 Nm (900 lb-ft) torque. The other two engine options consisted of a 5.7-liter Hemi V8 and a 6.4-liter unit.
