2024 Kenworth T680

Category, Truck, conventional sleeper road tractor. Mileage profile shows a high-use highway duty cycle, the kind of service that typically puts steady hours on the driveline and cooling system while concentrating wear on steer tires, brakes, kingpins, and cab contact points. Used condition at 512,713 miles puts this in the interval where maintenance history matters more than cosmetics, especially for aftertreatment health, charge-air plumbing, and any coolant or oil seep points. Powertrain details are not provided, so engine family, transmission model, and axle ratio cannot be tied to a specific application. ECM status is not listed, so verification should include an ECM pull for hours, idle percentage, fault history, and any derate events, then cross-check against dash mileage for consistency. Frame rails and crossmembers should be checked for straightness, corrosion at fastener points, and any evidence of prior repairs around suspension hangers. Fifth wheel top plate wear, slider operation, and air line routing are common inspection points at this mileage. Cab upholstery, sleeper seals, and door hinges tend to show the real duty cycle, look for pedal wear, steering wheel shine, and seat base play, then confirm HVAC output and bunk functions during a warm idle. Identification for records, VIN 1XKYD49X5RJ333028, stock 0633120.
