It's the second running of the Four Wheeler magazine Top Truck Challenge. It's Muck, sweat, and gears. For 15 years Four Wheelers Top Truck Challenge has been the pinnacle event of extreme off-road wheeling. No other off-road event even comes close to capturing the emotion of extreme wheeling and this edition is a classic. Voted into the event by the readers of Four Wheeler magazine, the teams compete on 7 obstacles, all designed to take them out one-by-one. You'll see up close footage of their struggles and triumphs through the new Obstacle Course, Tow Test, Tank Trap, Hill Climb, Frame Twister, Mud Pit and Mini-Rubcon.
