The Ram 2500 has undergone improvements similar to the ones the Ram 1500 received. With a coil-spring rear suspension it now has a ride that is more civilized than competing heavy-duty trucks. Chrysler's powerful 383-hp, 5.7-liter V8 is the standard engine, but you can opt for the powerful 6.7-liter Cummins turbodiesel. This strong-pulling diesel engine is not available on the Ram 1500. The truck lends itself easily to fifth wheel towing. It has two rear cameras: one for backing up, another for monitoring what's in the bed. The crew cab's rear seat is very roomy. Reliability of the turbodiesel version has dropped to well below average.
