2016 Mack CHU613

Duty cycle shows up as mid-mileage highway and regional work, 351,546 miles suggests it has seen steady use without being at end-of-life by odometer alone. Daycab layout points to drop and hook, local distribution, or yard and port style turns where sleeper space is not needed. Powertrain details are not provided, so verification should focus on what is on the truck now, engine family tag, transmission model tag, and rear axle ratio from the axle housings or build sheet. ECM status is not listed, so confirm active and inactive fault history, aftertreatment health data, regen frequency, and any derate events before assigning it to a route. Frame rails and crossmembers should be checked for straightness, rust scale, and evidence of prior repairs around suspension hangers and steering gear area. Fifth wheel condition is a wear item on daycabs, inspect top plate grooves, jaw wear, slider rail play, and air lines and electrical pigtails for chafe. Cab interior and controls should be evaluated for work-truck wear, seat base looseness, pedal pad wear, HVAC output, and gauge and switch function. Brake and tire condition should be read as a set, lining thickness, rotor or drum condition, tire match and remaining tread, and any uneven wear that points to alignment, kingpin, or suspension bushing needs.
