2020 Mack ANTHEM

Category, Truck (conventional sleeper), used, 312,000 miles. Mileage profile points to a highway duty cycle with typical wear centered on driveline lash, steer axle components, and sleeper hardware rather than low-mileage corrosion or idle-hour fatigue. Serial 1M1AN4GY4LM010780, stock B3811P. Powertrain details are not provided, so verification should focus on engine family, transmission model, and rear ratio from the VIN build sheet and dash/door tags, then match that to the intended work, long haul versus regional. ECM status is not listed, so confirm calibration history, fault counts, and any recent derates with a proper scan, then compare to service records for aftertreatment events and sensor replacements. Frame rails and crossmembers should be checked for straightness, drilled holes, and any signs of fifth wheel slider wear patterns that suggest frequent repositioning or heavy pin weight. Front axle and steering gear deserve a hands-on check for kingpin play, tie-rod end looseness, and uneven steer tire wear that can point to alignment drift or bushing wear. Sleeper interior and cab touch points should be evaluated for real-world use, seat base play, pedal wear, HVAC performance, and bunk hardware integrity. Brake and wheel-end condition should be confirmed by lining thickness, rotor or drum condition, hub seal seepage, and ABS lamp history, then backed up with a short road test for pull, vibration, and shift quality.
