What was the deal with that duramax dually? I seen him go the distance, about 340 feet, he had to be on propane (cheating), whats up, any thoughts on this and why did'nt anyone cry foul, or ask to look under his hood. The four tires in the back must have been filled with concrete. We left before the second round, how did he do with the sled weight moving rate dialed up?
