Mega Cab Diesel 2006 Dodge Ram 2500 4X4. Please call, vehicle is currently in Demo status. This truck is nicely equipped with features such as Cummins 5.9L I6 HO 600 Turbocharged and 4WD. New Car Test Drive said it ...offers a much smoother ride and a bigger, more comfortable, and more convenient cab. But all this refinement doesn't mean the Dodge Ram has gone soft...also delivers improved towing and hauling capability, plus more powerful and efficient engines... This rig runs, looks, and drives like a dream, but has tough enough looks that nobody thinks you've gone soft.
