The last race on Sunday was the Pro 4 Unlimited vs. Pro 2 Unlimited where all the big trucks play together at once. The 4WD trucks with the faster lap advantage started a half lap behind the 2WD trucks. After some crashes, carnage, and a few caution flags, Carl Renezeder had pushed his Pro 4 toward the front of the pack. He would move to the lead and become the first driver to win the big truck class Challenge Cup twice. Rob MacCachren would roll across the finish in Second Place overall with the top-finishing 2WD truck.
