Rick and Toni Skyberg of Poteau, Okla., run this 1993 Peterbilt 379 from Oklahoma to Arizona weekly hauling flagstone for landscaping applications. Rick Skyberg says the truck, which is powered by a 480-hp Detroit Diesel and a 10-speed transmission, has custom paint and custom-built fiberglass. “She’s a work in progress,” he says. “But she’s a head turner just the way she sits.”
