Although half-ton pickups sell in notably higher numbers, it's the three-quarter-ton and 1-ton models that do most of the heavy lifting. In the relatively small world of heavy-duty trucks, the 2014 Ram 2500 and 3500 HD reign supreme in terms of all-out capability. For instance, the Ram 3500's available Cummins turbodiesel cranks out a colossal 850 lb-ft of torque for a class-leading 30,000-pound tow rating. 2014's Ram 2500 models benefit from a new segment-exclusive multilink coil rear suspension for better on-road comfort than the outgoing leaf-spring setup. Rival pickups like the Chevy Silverado HD (or its GMC clone) and Ford's Super Duty offerings come close, but when it comes to blending harmonious levels of capability and refinement, the Ram 2500/3500 HD remains our top pick.
