The conclusion of an era came with the auction of the final Peterbilt 389 model, the 2025 Peterbilt 389X. This powerhouse features a 605-horsepower Cummins X15 engine, an Eaton-Fuller 18-speed transmission, and a 72-inch sleeper cab. Its design echoes the 1965 Peterbilt Model 358, paying homage to Rush Truck Centers’ founding year.
This iconic truck sold for $1.5 million to Rush Truck Centers, with proceeds going to charity. A significant $500,000 raised from sweepstakes entries benefited the Wounded Warrior Project, an organization dedicated to supporting veterans.
Jennifer Best of Pryor, Oklahoma, was the lucky winner of the sweepstakes and now proudly owns the rare 389X. She and her husband Shane co-own Shane Best Trucking, which primarily serves the construction and roadwork industries. “We do construction, road work,” Shane Best explained. “My family’s done it. My dad was in trucking, her dad was in trucking.”
Initially, Jennifer found it hard to believe. “I couldn’t believe it. We thought they were kidding with us,” she said. Rather than putting the truck to work, the Bests plan to collaborate with Tulsa’s Rush Truck Center to turn the 389X into a custom showpiece. “Oh no. We really want to keep it around” for posterity, Shane added.
The truck was presented at the American Trucking Associations’ Management Conference at Nashville’s Music City Center. Jessie Carzoli of the Wounded Warrior Project expressed gratitude for the support. “We will put it directly into programs and services that matter so much to our veterans,” she said.
In addition to supporting the Wounded Warrior Project, proceeds from the truck’s sale also went to Truckers Against Trafficking and Wreaths Across America, both causes closely connected to the trucking community.
Reflecting on the event, Rusty Rush said, “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.”
As for the future of the truck, Shane hinted that it might make its debut as a showpiece at next year’s Guilty by Association Truck Show in Joplin, Missouri.
