2021 International LT625

Duty cycle shows up in the odometer, 540,936 miles points to steady highway time and a truck that should be judged on drivetrain service history, aftertreatment health, and cooling system upkeep rather than cosmetic miles. Powertrain details are not provided, so engine family, transmission model, and axle ratio cannot be matched to a specific application. ECM status is listed blank, so an ECM report, fault history, and regen counts should be pulled before putting a number on aftertreatment risk. Frame rails and crossmembers are the first stop on a high-mileage sleeper, look for straightness, prior welds, and corrosion around suspension hangers and rear crossmember. Fifth wheel condition should be verified for jaw wear, top plate grooving, and slider rail play, with air lines and electrical pigtail checked for chafe. Cab interior wear typically tracks driver turnover at this mileage, inspect seat base play, pedal pad wear, dash switch function, and HVAC performance. Sleeper components to verify include bunk hardware, cab shocks, and air leaks, with a road test focused on steering wander, brake balance, and any vibration under load.
