Duty cycle suggests vocational service, 167,145 miles is consistent with dump work where idle time and PTO hours can matter as much as odometer miles. Serial 1NPCL4EX2LD655994, stock B3711, used condition, ECM data not provided, so aftertreatment history, regen frequency, and fault trends should be verified with a scan and a road load check. Powertrain details are not listed, so engine family, transmission model, and axle ratio cannot be matched to haul profile from the provided data. Application fit should be confirmed by checking for PTO provision, wet kit plumbing, and driveline angles under load, along with a review of maintenance records for clutch wear, u-joints, and differential service intervals. Frame rails on dump applications take concentrated stress at the hoist saddle and rear suspension hangers, inspect for flange cracks, added welds, and fastener elongation. Hoist and body mounts should be checked for pin slop, cylinder seepage, and scissor or telescopic pivot wear, plus evidence of bed twist from uneven dumping. Cab interior and controls should be evaluated for vocational wear, seat base play, switchgear function, and HVAC performance. Brake and tire condition should be judged by lining thickness, rotor or drum heat checking, and steer tire edge wear that can point to alignment or kingpin issues, with a close look at suspension bushings and steering linkage free play.
