New 2027 Peterbilt 579 Sleeper

Built for the road and equipped for long hauls, this 2027 Peterbilt 579 delivers premium comfort, capable performance, and practical versatility. The 80-inch high-roof Prestige sleeper gives drivers a well-appointed living space with a second bunk, coil-spring mattress, refrigerator, cabinet and drawer package, TV provisions, rear audio controls, and a fuel-fired sleeper heater.

Its 40,000-lb PACCAR rear axle, low-air-leaf suspension, 2.85 rear ratio, and 24-inch air-slide fifth wheel make it ready for general freight and flatbed service. Comfort and convenience continue with premium air-ride seats, heated power aero mirrors, Bluetooth audio, dual USB charging, a 1,800W inverter with shore power, and dual 120-gallon aluminum fuel tanks. Safety-focused equipment includes Bendix electronic stability control, ABS, tire-pressure monitoring, front air-disc brakes, a 15-inch digital display, and LED load lights.
