Cliff and Tracy Grace have owned this 2002 Kenworth W900L for eight years. Powered by a 475-hp 6NZ Cat with a 13-speed, the rig pulls a 2021 Walker food-grade tanker, hauling liquid sugar out of Chicago. The Graces redid all the chrome on the truck two years ago, and last year added a 2015 rear clip with new tires, brakes and more. Cliff, at 67, is still "truckin' strong" after 51 years on the road, he said.
