2016 Mack CXU613

Category, Trucks. Mileage profile points to a highway duty cycle with typical long-haul wear patterns, suspension bushings, driveline joints, and cooling stack condition are the areas that usually show it first at this age and usage. Serial 1M1AW21YXGM052175, stock B3380P. Powertrain details are not provided, so verification should focus on engine family, transmission model, rear ratio, and any active or inactive fault history pulled from the ECM. ECM status is listed blank, so plan on a full scan, aftertreatment health check, and a road test that confirms boost response, coolant temp stability, and shift quality under load. Frame rails deserve a straight look for corrosion scale, drilled holes, and any signs of previous repairs around suspension hangers and crossmembers. Fifth wheel condition should be judged by jaw wear, top plate scoring, and slider rail free play if equipped. Cab upholstery and sleeper interior should be checked for seat base looseness, pedal wear consistency versus odometer, HVAC performance, and any water intrusion at windshield and sleeper seams.
