Hummer envy anyone? This massive tank looks like a Wrangler that's taken more steroids than Barry Bonds, and shows that Jeep is tired of Hummer ruling as king of the off-road. The vehicle is based on the Dodge Ram Heavy-Duty and uses the same 5.9-liter Cummins turbo-diesel. It is loaded with gadgets like under-chassis cameras, infrared cameras, remote-control winches, and adjustable ride height. Rumor has it that this could be a preview of a plus-size Grand Cherokee variant.
