2021 Freightliner PT126064S T

Category, Trucks, conventional daycab. Mileage at 611,470 points to a highway-heavy duty cycle with typical high-wear focus areas being driveline joints, fifth wheel top plate, steer axle components, and air system integrity. Serial number 3AKJHLDV3MSMZ4666, stock 0632751. Powertrain, engine and transmission details are not provided, so application matching comes down to configuration and miles. Daycab layout favors terminal work, regional distribution, and slip-seat operation where cab access and HVAC performance matter more than sleeper amenities. ECM status is not listed, so verify active fault history, aftertreatment performance data, and any recent derate events through a scan report. Frame rails, look for straightness at the rear suspension hangers, crossmember rivet movement, and any added holes from prior equipment. Fifth wheel, check jaw wear, slider rail condition if equipped, and air release function, plus evidence of grease interval compliance. Cab interior, expect seat base wear, pedal pad wear, and door seal fatigue at this mileage, confirm all dash functions, window regulators, and air leaks at the steering column and brake valves during an air build and leakdown test.
