The Ram 4500 is about as extreme as it gets in this FCA brand's family of heavy-duty trucks. While the
2500 and
3500 are common as pickups, the 4500 is bought mostly in chassis cab form, making it easy for contractors and fleet buyers to have their own custom bodies bolted onto the back. The 4500 also comes exclusively with a dual rear wheel setup for maximum payload and towing capacities.
