'Caged Bronco

Darren Sinkey made a number of modifications to his big, well-heeled Bronco prior to Top Truck. The mods continued right up until it came time to leave for the event and as a result, he had no time to test the rig. He also came to the event with an aggravated leg injury from a previous dirt bike crash. Nonetheless, Sinkey was ready to compete.
