Like other heavy duty versions, the 3500 has a stiff ride that bounces passengers around. Choosing this heavy duty work truck over the regular 1500 lets you opt for a Cummins 5.9-liter diesel six-cylinder engine. Chrysler's 5.9-liter V8 and, for 2003, a 5.7-liter Hemi V8 was also available. The crew cab's rear seat is tight and upright. In 2011, the Ram pickups separated from Dodge and formed its own brand.
