The Ram 3500 mirrors the recent improvements that benefited the Ram 1500.
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 torque-rich 6.7-liter Cummins turbodiesel.
That strong-pulling diesel engine is not available on the Ram 1500.
There is also a 6.4-liter V8.
