The Ram 3500 provides something for everyone with the choice of three cab styles (regular, Crew and Mega cabs), four wheelbases, single or dual rear wheels and either 4x2 or 4x4 drive types. Power is provided by a 310-horsepower 6.7-liter Cummins diesel engine with a standard 6-speed manual or optional 6-speed automatic transmission. Available safety features include dual front airbags, curtain airbags and anti-lock brakes. Heated and ventilated front seats, heated rear seats, heated steering wheel, power adjustable pedals, rear parking sensors, and a rear backup camera are available. Electronic and infotainment choices include a multimedia system with 30-gigabyte hard drive, navigation system, SIRIUS Backseat TV, and a rear-seat DVD entertainment system. The Ram 3500 is redesigned for 2010. The Crew Cab replaces last year's Quad Cab.
