Compared with the 3500, the 2500 feels positively chuckable. In reality, it’s nearly as tough and just as unwieldy—for a truck—as its big brother, but unloaded and in single-rear-wheel configuration, it’s light enough to make a discernible difference. Even with a full payload of straw in the bed, it proved adept at wheeling along at freeway speeds. Just for grins we took a spin in a Hemi-powered 2500 (the Hemi is also available in the 3500 for 2013). It does the job, but with only 400 lb-ft of torque on tap, the gas V-8 lacks the grunt of the Cummins oil burner for serious haulers.Building a truck to handle extreme loads isn’t exactly rocket science, but to do it while retaining a modicum of drivability requires some finesse. Our time at the wheel was relatively free of jiggle and impact harshness, due in part to the updated frame made of high-strength steel, buttressed by eight cross members and fully boxed rear rails.*
