Overview This is a 2025 Peterbilt Model 548 Medium Duty flatbed truck (VIN 2NP8LJ9X6TM797161), fitted with a TEC steel platform flatbed body (Body #8-4525-24) built for other-commodity hauling in city delivery service. The chassis is finished in white (cab, hood, fenders, roof) over a black frame, rides on a 274-inch wheelbase, and carries a GVWR of 54,600 lbs with a 14,600-lb front axle load and 40,000-lb rear axle load. Engine & Drivetrain This truck is powered by a PACCAR PX-9 engine rated at 350 HP at 2,000 RPM, governed at 2,200 RPM, and producing 1,050 lb-ft of torque at 1,200 RPM (Productivity rating, 2024-series emissions, Model Year 2025 engine). It runs PACCAR's EMUX electronics architecture, with typical operating speed set at 65 MPH and the powertrain optimized for balanced, frequent start/stop duty cycles. Supporting components include a PACCAR 160-amp brushed alternator, two PACCAR premium 12V starting batteries (2,000 CCA), a PACCAR 12V starter, and a low-voltage disconnect system. Cold-weather and service features include an immersion-type block heater (110-120V), a Horton on/off fan clutch, an 18.7 CFM air compressor, a VGT exhaust brake, a high-efficiency cooling system, a single engine-mounted air cleaner, and a PACCAR fuel/water separator with a 12V heated fuel filter. Exhaust routes through a single right-hand DPF/SCR module under the cab, with a 36-inch chrome standpipe finished in clear coat. Power reaches the ground through an Allison 3000 RDS-P automatic transmission (Gen 6, Rugged Duty Series) in a 6-speed close-ratio configuration with neutral-at-stop and a dash-mounted push-button shifter, backed by a 1710 HD driveline with two midship bearings and a 1710 interaxle driveline for the tandem rear axles. PTO provisions include a Chelsea-style opening, a dash-mounted single-acting electric-over-hydraulic PTO control, LH-mounted trans PTO provisions, and a park brake interlock. Chassis & Axles Up front is a Meritor MFS+14F axle rated 14,600 lbs with a 3.5-inch drop and wide-track configuration, riding on taper leaf springs and shocks rated to 14,600 lbs, with Sheppard SD110 power steering, a frame-mounted reservoir, and greasable front spring pins. Front braking is handled by Meritor EX+L optimized air disc brakes with PHP10 Iron Preset+ hubs and severe-service disc brake rotors. The rear end uses a Meritor MT40-14X axle rated 40,000 lbs with a 5.29 ratio, a differential lock on the tandem axles with speed interlock, heavy-wall drive axle housings, and synthetic axle lubricant, with Meritor EX+L optimized air disc brakes and PHP10 Iron Preset+ hubs with severe-service rotors on the tandem drive. An anti-lock braking system (6S6M configuration) is fitted throughout. The frame consists of 10-3/4-inch steel rails (403"-444" range) at 3/8-inch thickness with a full steel inner liner, an HD 5-piece crossmember at the back of cab, aluminum frame rail crossmembers, and a custom wheelbase/overhang.
