Take the Diesel Power Truck Challenge, the world's largest diesel magazine. 10 Trucks Entered and less then half made it out! It's power, durability, and efficiency. Hundreds of readers from across the country were considered, but only 10 were chosen. They had no idea what they were getting into. This running of the Diesel Power Challenge was the toughest, most challenging yet. Seven torture tests awaited the competitors in Denver, Olorado, and only the strongest vehicles and most experienced drivers would finish. See all the power, smoke, torque, and destruction right here on the Diesel Poser Challenge DVD. Cummins, Duramax, and Power Stroke engines slug it out, but only one can be champion.
