The 2018 NASCAR Camping World Truck Series was the 24th season of the third highest stock car racing series sanctioned by NASCAR in North America. Christopher Bell entered as the defending champion, but he did not defend his championship, leaving his No. 4 Kyle Busch Motorsports entry to a number of drivers throughout the season, with Todd Gilliland covering the majority of the schedule in the truck. Title sponsor Camping World Holdings rebranded the series with their Gander Outdoors brand they acquired in 2017 for the 2019 season, replacing the Camping World brand.

Christopher David Bell is an American professional stock car racing driver. He competes full-time in the NASCAR Cup Series, driving the No. 20 Toyota Camry XSE for Joe Gibbs Racing and part-time in the NASCAR Craftsman Truck Series driving the No. 1 Toyota Tundra for Tricon Garage. He is the 2017 NASCAR Camping World Truck Series Champion.
