This is the Freightliner Sport Chassis P4XL. It is a limited production truck with a Cummins ISC 330 diesel putting 1000 ft/lb to the ground at the rear tires. Towing rate just under 30,000 pounds with a 15,000 tongue. Oakley sunglasses signed up for the first three trucks as mobile advertising vehicles. And the one I saw had Italian leather interior with a suede headliner and 4 TV's.
