Rocky Mountain Grades, Fuel Economy and Sled Pull Action!Having the fastest diesel powered pickup truck in North America is a pretty big deal but what use is it if it can’t climb a mountain pass without breaking a sweat or running out of diesel fuel. In our opinion, Diesel Power Challenge competitor trucks should exemplify what a real world diesel truck is. A full bodied truck that can haul, tow, lay down some serious power and all while achieving respectable fuel economy. This is why we save our last day of Diesel Power Challenge for our 142-mile Fuel Economy Drive through the steep grades and mountain passes of the Rocky Mountains before making each truck hook up to a seriously heavy weighted sled to test their limits.
