2018 NASCAR Camping World Truck Series

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.

This was the third year that the Truck Series (and the Xfinity Series) had a playoff system. For the first time in the three years of the playoffs at that time, Christopher Bell and Matt Crafton were not part of the "championship 4" drivers competing for the title at Homestead. Bell had moved up to the Xfinity Series full-time, while Crafton did qualify for the postseason but did not advance to the last round of the playoffs as he had done the past two years.

The 2018 season was also the first to feature the regular season championship trophy, which was awarded at the final race before the playoffs.^[1] Johnny Sauter clinched the NCWTS Regular Season Championship trophy at the end of the UNOH 200 at Bristol Motor Speedway.^[2] Brett Moffitt was declared the NCWTS Champion for 2018, after winning the Ford EcoBoost 200 at Homestead-Miami Speedway.
