Last 389 ever built -- 2025 Peterbilt 389X
This last 389 ever built is a 2025 Peterbilt 389X, powered by a 605-hp Cummins X15 with an Eaton-Fuller 18-speed and outfitted with a 72-inch sleeper. This one-of-a-kind 389's exterior was designed to match the paint scheme of the 1965 Peterbilt Model 358 that is displayed at Rush Truck Centers’ headquarters, commemorating the year the company was founded.

The absolute last of the iconic Peterbilt 389 models ever built, a 2025 Peterbilt 389X auctioned by the manufacturer to Rush Truck Centers with a winning $1.5 million bid, has found its final home. Monday in Nashville, Tennessee, small fleet operator Jennifer Best of Oklahoma was unveiled as the winner of Rush Truck Centers' subsequent sweepstakes to take home the 389X, with another $500,000 collected from sweepstakes entrants and delivered to the nonprofit Wounded Warrior Project, supporting veterans in need.

Jennifer and Shane BestJennifer and Shane Best own and operate 17-truck Shane Best Trucking out of Pryor, Oklahoma, and planned to work with the Tulsa, Oklahoma, Rush Truck Center to finish out the 389X as a custom show unit.Unless otherwise noted, all photos by Todd DillsThe Bests own and operate dump trucks and tractors with end dump trailers. "We do construction, road work," said Shane Best. "My family's done it. My dad was in trucking, her dad was in trucking."

Notified ahead of the official giveaway that she was the winner of the sweepstakes, Jennifer Best said she thought it was a joke at first. Tulsa Rush Truck Centers reps, folks the Bests know well as they operate an entirely Peterbilt fleet, called with the news, and "I couldn’t believe it" at first, she said. "We thought they were kidding with us."

They'll work with the dealer's shop to "finish out the back" of the truck, Shane said, for show.

Any plans to put the truck to work? "Oh no," Shane said. "We really want to keep it around" for posterity.  

Jessie Carzoli, Wounded Warrior Project associate director for corporate partnerships, thanked Rush Truck Centers and all sweepstakes entrants for what she called an "unheard of" donation amount for a first-year partner. "We will put it directly into programs and services that matter so much to our veterans," Carzoli said, suicide prevention and other mental health support among the organization's principal missions.

"We'll get you a smaller one," Rush quipped in the aftermath of the check presentation."We are one of the only large nonprofits that does not accept government funding," she added. "Donations from individuals and from companies are so much more important for us." 

Wounded Warrior Project wasn't the only nonprofit that benefited from the proceeds generated by the only 2025 model year Peterbilt 389X ever built. The $1.5 million winning bid and purchase, as previously reported, was split between Truckers Against Trafficking and Wreaths Across America, both organizations with close ties to the trucking industry.  

Concluding the presentation of the truck to the Bests, Rush Enterprises CEO Rusty Rush reflected on the sweepstakes, noting “it’s been a great day and an exciting day. It’s been very special ... a great past 6-8 months putting this together -- trailering the truck around the country."

To the Bests, don't worry, Rush added, "we didn’t put any miles on it." 

With any luck on the rest of the build, look for the finished rig potentially in time for next year's Guilty by Association Truck Show in Joplin, Missouri, Shane Best said.
