Duty cycle suggests a vocational life, 275,000 miles on a dump spec typically points to mixed on road and jobsite time with frequent PTO cycles, heat soak, and stop and go loading. Serial number 1NPCXPTX7PD870124, stock 0633409. Powertrain details are not provided, so verification matters, engine family, transmission model, rear ratio, and PTO provision determine whether it is set up for short haul aggregate, asphalt, or heavier off road pulls. ECM information is not listed, so plan on pulling an ECM report to confirm total miles, idle hours, and any active or inactive fault history. Frame rails and vocational mounting points are the first walkaround items, look for rail top flange scuffing near hoist mounts, crossmember cracking, and any added brackets that show elongation or fresh hardware. Hoist, body pivots, and tailgate hardware should be checked for pin wear, bushing play, cylinder rod pitting, and hydraulic seep at fittings and pump, especially around the PTO and reservoir area. Cab entry points and controls tend to tell the story on dump work, inspect seat base looseness, pedal wear, and switchgear for PTO, diff locks, and traction controls if equipped. Cooling stack cleanliness, charge air boots, and driveline U joints are routine wear items on this kind of service, inspect for oil misting, clamp witness marks, and driveline slop before putting it back into daily cycles.
