2024 Kenworth T680

Category, Truck, conventional sleeper. Mileage profile points to highway duty cycles and steady seat time, so the value conversation centers on maintenance history, aftertreatment health, and cab wear rather than cosmetic add-ons. Serial 1XKYD49X9RJ333047, stock 0633122. Powertrain details are not provided, so verification should focus on engine family, transmission model, rear ratio, and any active or stored fault history. ECM information is not listed, so an ECM report pull and a regen history check are key to confirming aftertreatment performance and identifying patterns like frequent parked regens, derates, or repeated sensor replacements. Frame rails and suspension points are the first walkaround items at this mileage, look for rail flange rust scale, cracks around suspension hangers, and evidence of prior repairs at crossmember rivet lines. Fifth wheel top plate, slide rails, and locking jaw wear should be checked for uneven contact patterns and excessive free play. Cab upholstery, sleeper trim, dash switches, and steering wheel wear typically tell the truth about driver turnover, while air system behavior, compressor cycle time, and air dryer purge consistency help confirm the condition of the pneumatic side without guessing at unseen components.
