The NASCAR Camping World Truck Series (formerly the NASCAR SuperTruck Series presented by Craftsman and the NASCAR Craftsman Truck Series) is a pickup truck racing series owned and operated by the National Association for Stock Car Auto Racing. It is the only series in all of NASCAR to race modified production pickup trucks and is one of the three national divisions of NASCAR, together with the Nationwide Series and the top level Sprint Cup Series. On December 3, 2007, Sears Holdings Corporation announced that, at the conclusion of the 2008 season, its Craftsman brand would no longer sponsor the series.[1] Craftsman had been the title sponsor since 1995, the year NASCAR founded the series. It was replaced as a sponsor by Camping World.
