The big Cummins diesel 6-cylinder that's available in 2500 and 3500 HD models is unlike anything else on the market--with the attitude and torque curve of a tractor-trailer engine. It, plus a number of other upgrades for 2013, give the heavy-duty Ram 3500 editions an astonishingly high maximum tow rating of 30,000 pounds.
Ram 2500 models are intended for the most extreme personal-towing needs, while the 3500 models are aimed at heavy commercial use by ranchers or construction crews. With diesel models' 10-percent gain in fuel efficiency, as well as other maintenance-related improvements, running costs should be down versus these trucks' predecessors.
Even compared to the other latest heavy-duty trucks, the Ram 2500 and 3500 HD models have some of the best-appointed, most luxurious and most attractive interiors, picking up much of the look and some of the high-line materials from the latest light-duty Ram trucks.
