2024 Mack ANTHEM

Duty cycle shows as lower-mile highway use at 141,000 miles, the kind of number that typically points to linehaul or regional runs rather than stop-and-go vocational work. Condition is used, so the value is in verifying service history, idle time, and how the miles were accumulated. Powertrain details are not provided, so the inspection focus should stay on what can be confirmed, engine brake operation, transmission shift quality under load, driveline vibration on acceleration and coast, and any active or stored fault codes pulled from the dash and ECM. ECM information is not listed, so plan on a scan tool report and a road test to validate aftertreatment behavior, regen frequency, and any derate history. Frame rails and crossmembers should be checked for fresh paint, drilled holes, or flange distortion that can indicate prior upfit or repairs. Fifth wheel top plate wear, slider rail condition, and air line routing are key wear points at this mileage, along with steer tire feathering that can hint at alignment or kingpin play. Cab and sleeper condition should be judged by seat base play, pedal wear, and bunk hardware, those areas usually tell the truth about driver use. Cooling stack cleanliness, charge-air piping clamps, and battery box corrosion are practical walkaround items, and any wetness at hubs, pinion seals, or around the engine front cover should be noted as early leak indicators.
