Hank O’Neill drives this 2000 Kenworth W900 with a 565-horsepower Cummins and 18-speed under the hood. The truck features an extended hood and studio sleeper. The only custom work on the truck is the 7-inch dual straight stacks. O’Neill uses the truck to haul a petroleum tanker from his home base in Las Vegas to all over Nevada, Arizona and Utah. A regular run is from Las Vegas to Lupton, Ariz., with a load of transmix (a mix of diesel and unleaded gasoline that is unavoidable when changing products in a pipeline) and a backhaul of unleaded gas.
