Overview

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. Key dimensions include a 67.5-inch FAX/BOC, a 206.5-inch cab-to-axle, and a 313.3-inch cab-to-EOF, with a maximum grade rating of 6 percent. A steel tapered chrome bumper with two tow points finishes the front.

Suspension
The rear suspension is a Hendrickson HMX EX 400 rated 40,000 lbs with 54-inch Haulmaax springs and a 60K creep rating, complemented by a cab air suspension for ride comfort.

Cab & Interior
The cab is a Peterbilt Aero 107-inch BBC design with an SMC hood featuring a molded charcoal crown and aluminum cab construction, finished inside with a ProBilt charcoal gray interior, curved roof, and a thermal insulation package. Seating consists of Sears driver and passenger seats, with the driver's seat featuring air-ride, high-back, and vinyl trim and the passenger seat non-air-ride, high-back, and vinyl trim, along with driver armrests on both sides and a toolbox under the passenger seat. The cab includes a tilt/telescoping adjustable steering column with a Peterbilt-logo steering wheel, a one-piece curved windshield, a fixed one-piece glass rear window (day cab), power door locks and power windows, electric wipers with an intermittent feature, and a combination fresh-air heater/air conditioner.

Body & Equipment
This unit is outfitted with a TEC steel platform flatbed body (Body #8-4525-24) measuring 102 inches wide (length pending confirmation — see flag above), built on 7-inch structural channel longsills with 4-inch structural channel crossmembers on 12-inch centers, gusseted every other crossmember, and a 3/16-inch smooth floor. The underside of the body is fully undercoated with a petroleum-based undercoating, and the body features a formed side rail with stake pockets and a full-height bulkhead with a window cut-out, finished in black enamel. Lighting and safety equipment on the body include an LED marker light kit (3/4 bullet style), reflective white conspicuity tape on both sides (stitched) and the full-width rear, HD ICC underride protection, and anti-sail mudflaps, all on a 12-volt DC system. Equipment includes an underbody toolbox on the driver's side, seven 4-inch winches and straps mounted on a slider rail on the passenger side, a winch bar holder mounted on the bulkhead, a 3-point access ladder at the bulkhead on the driver's side, and a genuine Moffitt/Princeton forklift carrier kit installed. On the chassis side, fueling is handled by a D-shaped aluminum 100-gallon fuel tank mounted LH under cab with a non-slip step, paired with a small/HD 14-gallon DEF tank mounted LH BOC with a polished stainless steel cover and a 1:1 DEF-to-fuel ratio; the chassis is confirmed centrally fueled, with two low-flex steps under cab. Electrical connections include a 7-way electric harness socket-mounted at the EOF, body connections 5 feet BOC, and a body connection with a Trucklite junction box at the LH EOF. An aluminum space-saver battery box is mounted RH BOC with side access, and an aluminum non-slip cab entry step covers the RH under-cab aftertreatment area. Air system components include a Bendix AD-HF air dryer with heater and coalescing filter, pull cords on all air tanks, nylon chassis hose, and steel painted air tanks.
