2024 Kenworth T680

Duty cycle signals point to highway miles, with 388,200 showing steady use rather than low-hour yard work. Conventional sleeper layout fits long stretches between stops, with the kind of wear you expect to find first in driveline slack, steer components, and cab contact points. Powertrain details are not provided, so verification matters, engine family, transmission model, and rear ratio should be confirmed off the door tag, build sheet, or ECM pull before matching it to a lane. ECM status is listed blank, so an electronic health report and aftertreatment history check are key, look for parked regen frequency, fault history, and any recent derate events. Frame rails and crossmembers should be checked for straightness, corrosion at fastener points, and any added holes from accessory mounting. Fifth wheel top plate, slide rails, and locking jaws are the wear areas to inspect for dry spots, uneven contact, and jaw bite. Cab interior condition will tell the story on how it was operated, seat base play, pedal wear, steering wheel shine, and sleeper upholstery seams typically correlate with driver turnover and maintenance habits. Cooling stack cleanliness, charge air piping clamps, and air system moisture at the tanks are practical walkaround checks that often predict near-term downtime.
