2020 Mack ANTHEM

Category, Trucks. Mileage profile suggests highway duty cycles with steady heat soak and long service intervals, so inspection priority should be blow by, CAC plumbing integrity, and aftertreatment history rather than stop and go brake wear. Identification tags include VIN 1M1AN4GY4LM014599 and stock B3530P for cross checking maintenance records, fault history, and campaign completion. Powertrain details are not provided, so verification should focus on engine family, transmission model, and rear ratio as a matched set. ECM data is listed as blank, so a laptop pull is warranted to confirm total engine hours, idle percentage, regen counts, derate events, and any active or stored codes that would explain recent repairs or drivability complaints. Frame rails and crossmembers should be checked for straightness, corrosion at fastener points, and any added holes or weld repairs around suspension hangers and fifth wheel area. Fifth wheel jaws, slide rails, and air lines are wear points at this mileage, look for jaw wear, cracked top plate, and air leaks under charge. Cab upholstery, sleeper trim, and door seals typically show the real duty cycle, check seat base play, pedal wear, HVAC function, and water intrusion around windshield and marker light penetrations.
