2020 Mack ANTHEM

Category, Trucks. Mileage profile points to a highway and regional daycab duty cycle, enough time on the clock to justify a close look at consumables and chassis wear points. Serial 1M1AN3GY9LM015337, stock B3877L. Powertrain details are not provided, so engine family, transmission model, and rear ratio should be verified off the VIN build sheet and dash tag data before matching it to a specific route, weight class, or cruise speed. ECM status is not listed, so confirm calibration history, fault counts, and any recent aftertreatment events with a scan report. Frame rails and crossmembers should be checked for drilled holes, added brackets, and corrosion at fastener points, common tells of prior upfit changes. Fifth wheel and slider rails, if equipped, need inspection for jaw wear, lock test, and grease condition, plus air line routing and gladhand condition at the back of cab. Cab interior wear on seat base, pedal pads, and steering wheel rim typically tracks true hours better than odometer, useful for judging how hard the daycab cycle has been.
