2021 International LT625

Category, Truck. Mileage profile, 439,483 miles puts it in a highway duty cycle bracket, expect normal long-run wear points like steer tire edge wear history, driveline angles, and fifth wheel top plate condition to tell the story. Serial 3HSDZTZR6MN073923 and stock 0635109 give traceability for service records, recalls, and campaign work. Powertrain data, engine, transmission, axle ratio, and ECM details are not provided, so application fit cannot be tied to gearing or shift strategy from the listing alone. ECM field is blank, verify calibration history, fault code count, and aftertreatment health with a scan tool pull, then match that to any maintenance documentation. Cab and chassis walkaround, focus inspection on frame rail straightness around suspension hangers, air system leaks at tanks and fittings, and evidence of prior fifth wheel slide movement or cracked mounting bolts. Sleeper interior wear at seat bases, bunk hardware, and dash switchgear tends to correlate with overall care at this mileage, check HVAC performance, bunk HVAC if equipped, and look for coolant residue at heater core connections and firewall pass-throughs.
