2025 Kenworth W900L

Category, Trucks. Mileage profile, 147,500 miles suggests early-life highway or mixed-duty service rather than end-of-cycle wear, with most evaluation value in maintenance records, fluid sampling, and any early warranty or campaign documentation tied to the VIN 1XKWD49XXSR157012. Condition is listed used, so inspection should focus on signs of break-in debris, seepage at common gasket points, and any evidence of hard pulls or extended idle time. Powertrain documentation, ECM details are not provided, so verify engine family, horsepower rating, aftertreatment configuration, and transmission model from the build sheet and dash data. ECM hours, idle percentage, regen history, and fault code log are the quickest indicators of duty cycle and aftertreatment health, with special attention to repeated NOx efficiency, DPF differential pressure, or derate events. Frame rails, look for straightness, paint rub-through, and fastener witness marks around suspension hangers and crossmembers that can indicate prior component replacement. Fifth wheel, check jaw wear, top plate scoring, slider rail condition, and air line routing for chafe. Cab upholstery and sleeper trim, inspect seat bolster wear, pedal pad wear, and switchgear shine to confirm the mileage story, then confirm HVAC performance, bunk HVAC if equipped, and any water intrusion at door seals and sleeper pass-through.
