2022 Kenworth T680

Duty cycle shows up in the odometer, 556,100 miles points to highway miles and fleet-style utilization rather than short-hop stop and go. Conventional sleeper layout suits long stretches between stops, with the kind of cab storage and bunk space drivers expect for overnights and multi-day runs. Powertrain details are not provided, so the evaluation stays focused on what can be verified from the listing. ECM status is not listed, so plan on pulling an ECM report and comparing it to dash mileage, idle hours, and any logged fault history before putting a number on remaining service life. Frame rails and crossmembers are the first stop on a walkaround at this mileage, look for straightness, corrosion at fastener points, and any evidence of added holes or repairs around suspension hangers and fifth wheel area. Fifth wheel and slider rails should be checked for jaw wear, pivot slop, and dry spots, with attention to air line routing and chafe points. Cab upholstery and sleeper trim typically show the real story of driver care, check seat base play, steering wheel wear, and bunk hardware for looseness. Cooling stack, charge air piping, and engine bay harness routing should be inspected for oil misting, rub-through, and clamp integrity, with a close look at any seep points around valve cover, front cover, and aftertreatment connections.
