2021 International LT625

Category, Truck (conventional sleeper). Mileage profile, 539,411 miles points to a highway-heavy duty cycle where cab time, cooling system upkeep, and aftertreatment health matter more than body wear. Serial 3HSDZAPR7MN826351 and stock 0633114 give a clean reference for service history, recalls, and any campaign work. Powertrain, engine, transmission, axle ratio, and ECM details are not provided, so application fit cannot be pinned down beyond general sleeper use. ECM status is listed blank, so verification should include pulling an ECM report for hours, idle percentage, fault history, and any evidence of programming changes. Cab structure, sleeper and interior wear should be judged by seat base play, pedal and steering wheel shine, bunk hardware, HVAC performance, and dash switch function, since those items track true duty cycle at this mileage. Frame rails, crossmembers, and fifth wheel area deserve a close look for corrosion, elongated mounting holes, cracked paint around suspension hangers, and slider travel, along with air system leak-down and driveline u-joint play during a yard inspection.
