2021 Kenworth T680

Duty cycle shows up in the odometer, 527,000 miles puts it in the high-mileage highway class where maintenance history and wear items matter more than cosmetics. Identification points are straightforward for verification, VIN 1XKYD49X5MJ467773 and stock 0633111. Powertrain details are not provided, so engine family, transmission, and axle ratio need to be confirmed before assigning a lane, long haul versus regional, heavy versus light. ECM information is listed blank, so an ECM printout or diagnostic report is the cleanest way to verify calibration, fault history, and aftertreatment status. Cab and sleeper condition should be judged by touch points and noise, seat bases, steering wheel wear, pedal pads, bunk hardware, and HVAC performance under load. Chassis inspection should focus on typical high-mileage wear, fifth wheel jaw wear and plate condition, air system leaks, brake chamber and slack adjuster travel, steer tire feathering, and any seepage at hubs, power steering, and coolant joints.
