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. Johnny Sauter clinched the NCWTS Regular Season Championship trophy at the end of the UNOH 200 at Bristol Motor Speedway. Brett Moffitt was declared the NCWTS Champion for 2018, after winning the Ford EcoBoost 200 at Homestead-Miami Speedway. In addition, Hattori Racing Enterprises won the NCWTS Owners' Championship.

Schedule
The final schedule – comprising 23 races – was released on May 23, 2017.

Schedule changes
In 2015, NASCAR and 21 Camping World Truck Series tracks agreed on a five-year contract that guarantees each track would continue to host races through 2020. Despite the agreement, Speedway Motorsports decided to cancel the New Hampshire Motor Speedway race and add a second race at Las Vegas Motor Speedway, to form two weekends involving each of the three national series. The new race will be the third race of the regular season, while the established fall race will be the second race of the first playoff round.

As a result, the Chevrolet Silverado 250 at Canadian Tire Motorsport Park will be held as the first race of the playoffs, while the Overton's 225 at Chicagoland Speedway will move from September to June. The UNOH 200 at Bristol Motor Speedway will become the final race of the regular season as a result of the schedule realignment.

Unlike the 2017 schedule, the JEGS 200 at Dover International Speedway will precede the 37 Kind Days 250 at Kansas Speedway and the North Carolina Education Lottery 200 at Charlotte Motor Speedway. Also, the Eaton 200 at Gateway Motorsports Park will be held one week later as the tenth race of the season, slated to be held the week before the Chicagoland round.

On April 17, 2018, Bristol Motor Speedway announced the UNOH 200 will be moved one day to Thursday night, August 16. The new race date will also reflect a change from FS1 to Fox, as the race broadcast moves to the broadcast network. The live Thursday night race on Fox coincides with preparation for Fox to broadcast the majority of Thursday games during the 2018 NFL season. Fox will now air two Truck Series races, both during the second half of the season when NBC has the Monster Energy NASCAR Cup and Xfinity Series coverage.
