2022 Kenworth T680

Duty cycle shows up in the odometer, 332,850 miles on a late-model daycab points to highway and regional turns rather than short, stop-and-go yard work. Use case fits drop-and-hook, terminal shuttles, and day-rate lanes where aero efficiency and cab access matter more than sleeper storage. Powertrain details are not provided, so evaluation stays at the chassis level. VIN 1XKYD49X5NJ148410 and stock 0635859 are the identifiers to match against build sheet, engine family, aftertreatment configuration, and transmission model before any spec-dependent claims, ECM data is not listed, so hours, idle percentage, and fault history should be pulled during inspection. Cab structure and controls on this platform typically show wear first at the driver entry steps, grab handles, seat base, and steering wheel finish, those touch points tell you how hard the truck has been cycled. Frame rails and suspension hangers should be checked for straightness, rust scale at fasteners, and any evidence of curb strikes, while the fifth wheel top plate, slide rails, and release handle condition will indicate coupling frequency and maintenance habits. Aftertreatment and cooling stack are the big-ticket inspection items at this mileage band, look for soot staining at clamps, heat shielding integrity, and harness routing at the DEF doser and NOx sensors. Tire wear pattern, brake lining remaining, and any play at kingpins and tie-rod ends will quickly confirm alignment health and front-end service needs.
