When you need to tackle serious hauling and towing, few full-size pickup trucks can match the Ram Heavy Duty's blend of capability and attitude. Available in regular cab, crew cab, and extended-length Mega Cab styles, the Ram 2500 and Heavy Duty models offer a choice between gasoline V8 and diesel inline six-cylinder power. Naturally, you can upgrade to four-wheel drive. Equipment ranges from basic to luxurious, and if you're planning to head well off the road, the 2500 Power Wagon specializes in traveling where pavement doesn't exist.
