Here's a unique piece of Roush Racing history up for sale at Mecum Auction: This is one of the four trucks used in the "Driver X" series on Discovery Channel, which was driven by Erik Darnell on his way to earning a full-time Truck ride for 2006.
This chassis, RRCT28, was retired from active duty prior to the series - a televised version of the Gong Show - being filmed.
