Chris Anderson and Chris McKendry have spent nearly all of their off-road forays in desert race vehicles. They had to quickly pick up some Jeep skills on the first day or risk tumbling to the bottom of the Morrison Trail switchbacks. Their Wrangler Unlimited Sport training vehicle rolls on 17x9 ATX beadlock wheels bolted to 40x13.50R17 Nitto Mud Grapplers. Clearance for the meaty tires is courtesy of EVO Double ThrowDown suspension and Poison Spyder tube fenders front and rear. The stock bend-prone front axle housing was tossed in favor of a Dynatrac ProRock 44 that was stuffed with RCV shafts. ARB Air Lockers are fitted in the front and rear axles.
