Overview This 2025 Peterbilt Model 548 day cab dump truck is spec’d for construction dump work, both on and off highway, hauling construction materials. It runs a 350 HP PACCAR PX-9 engine, an Allison 3000 RDS-P Rugged Duty Series automatic, and a Dana Spicer DSP41 40,000 lb tandem on Hendrickson HMX EX 400 HaulMaax suspension. It carries a 16' DuraClass MAB HPT 15-yard dump body with a FEE hoist and a Mountain electric tarp, and it’s rated at a 60,000 lb GVWR. The Aero 107" BBC hood, white Axalta two-stage paint and high-polish Alcoa aluminum wheels give it a clean, professional look on the jobsite. Engine & Drivetrain Power comes from a PACCAR PX-9 rated at 350 HP @ 2000 RPM, governed at 2200 RPM, with 1,050 lb-ft of torque @ 1200 RPM. It’s built to 2024 emissions standards. The powertrain is optimized for balance in service with frequent start-and-stop cycles, and typical operating speed is set at 68 MPH. A VGT exhaust brake, engine protection shutdown, a Horton on/off fan clutch, a high-efficiency cooling system, an engine-mounted air cleaner, an 18.7 CFM air compressor and a PACCAR fuel/water separator round out the engine package. Electrical components include a PACCAR 160 amp brushed alternator, a PACCAR 12V starter, two PACCAR Premium 12V starting batteries rated at 2000 CCA, a low voltage disconnect system, a battery disconnect switch mounted on the battery box, and a battery jumper terminal under the hood on the LH frame rail. The engine is backed by a Gen 6 Allison 3000 RDS-P Rugged Duty Series 6-speed automatic with close-ratio gears, a dash-mounted push-button shifter, a TC-421 torque converter, Allison Neutral at Stop, auto neutral with the parking brake, and an Allison transmission oil cooler. Power reaches the rear through a 1710 HD driveline with one midship bearing to a 4.88 rear axle ratio. For PTO work, the truck has LH transmission PTO provisions with a Chelsea PTO (F/O), a dash-mounted single-acting electric-over-hydraulic PTO control, a park brake interlock for the transmission-mounted PTO, a 12-pin remote PTO/throttle provision in the engine bay, and a 1400 RPM max PTO speed. Exhaust is a single RH system with a single-module DPF/SCR mounted RH under the cab, finished with an 18" tall, 5" diameter chrome standpipe with clear coat and a curved tip. Chassis & Axles The chassis rides on 10-3/4" steel frame rails with 3/8" rail thickness and a full steel inner liner. It uses aluminum frame rail crossmembers, a heavy-duty 5-piece back-of-cab crossmember with bolts instead of Hucks, and a square end of frame. Wheelbase is 206", with 67.5" from front axle to back of cab, 138.5" cab-to-axle and 209.5" cab-to-end-of-frame. Engineering-assigned ratings are a 20,000 lb front GAWR, 20,000 lb on each rear drive axle, and a 60,000 lb GVWR. Up front is a PACCAR FX-20 20,000 lb steer axle with a 4" drop and wide track, Sheppard HD94 dual-gear power steering, and a frame-mounted power steering reservoir with cooler. The rear is a Dana Spicer DSP41 40,000 lb tandem with tandem differential locks with speed interlock and synthetic lubricant in all axles. Braking is Bendix air cam drums, 16.5x6 front and 16.5x7 rear, with inverted rear brake chambers, rear brake camshaft reinforcement, gusseted cam brackets on the steer and drive axles, heavy-duty steer axle cam bushings, and a 4S4M anti-lock braking system. PHP10 iron PreSet+ hubs are used front and rear. Air equipment includes a Bendix AD-HF air dryer with heater and coalescing filter, painted aluminum air tanks with pull cords, nylon chassis hose, and an F/O air port fitting outboard of the driver seat. Suspension The rear suspension is a Hendrickson HMX EX 400 HaulMaax rated at 40,000 lbs with 54" axle spacing and a 60K creep rating. It has a double rebound strap kit and heavy-duty shock absorbers. The front uses 20,000 lb taper leaf springs with shocks, greasable spring pins, and 80 mm spring spacer blocks. Cab & Interior The day cab pairs an aluminum cab with a Peterbilt Aero 107" BBC SMC hood, a bright-finish hood crown, a charcoal gray Probilt interior with a curved roof, and a cab thermal insulation package. The driver sits in a Sears air-ride, high-back vinyl seat with LH and RH armrests, and the passenger has a Sears non-air, high-back vinyl seat. The cab rides on cab air suspension. A multi-function steering wheel with audio and cruise controls sits on a tilt/telescope column. Standard comforts include power door locks and windows, a combination fresh-air heater and air conditioner, a one-piece curved windshield, a fixed one-piece glass rear window, a stainless steel outside sunvisor, intermittent electric wipers, and a deep rear-wall record/map pocket. Visibility comes from motorized, heated Peterbilt Aero mirrors with integrated convex glass and a look-down mirror over the passenger door. For entertainment and communication there’s a ConcertClass AM/FM/WB radio with 3.5 aux input, Bluetooth phone and audio, a USB port, two cab speakers, and radio mute in reverse. The truck also has a Uniden Bearcat 880 CB radio with weatherband mounted in the center of the header, with dual LH/RH mirror CB antenna mounts. SmartLinq remote diagnostics are included. Instrumentation is a 7" digital cluster display that shows transmission oil temperature, air filter restriction, engine and PTO hourmeters, turbo boost, engine percent torque and a voltmeter. There’s also a backlit fuel filter restriction gauge, a dual-scale MPH/KPH speedometer, and three additional dash switches with wiring. Safety and convenience features include a textured, NFPA-compliant exterior cab entry grab handle, a passenger-side fire extinguisher, a triangle reflector kit, a 107 dB backup alarm, headlamps that turn on with the wipers, and self-canceling turn signals. Body & Equipment The truck carries a DuraClass MAB HPT 15-yard dump body, 16' long with 42" sides, an 84" inside width and a 96" outside width, rated at 14.5/17.2 yards. The body is built with 10 ga Hi-Ten steel on the front and sides, a 3/16" Hi-Ten rear, and a 3/16" AR450 floor. The interlaced frame has 8 ga Hi-Ten steel longmembers, with 4" crossmembers on 12" spacing interlaced through 10" longmembers. Heights are 60" at the front, 42" at the sides and 50" at the rear. The sides have insulated panels and at least three 4-1/2" forward-slanted vertical braces. The rear is sloped at 16°, with 28" rear cornerposts that have round light cutouts with two ovals. The single-acting tailgate has an electric/air release with an installed overcenter, a 1-1/2" upper hinge plate, and 6-panel bracing (one horizontal, two vertical). A 10" Sch 80 spill apron with a 30° sloped tailgate is included. Lifting is handled by a FEE A6-134-K60-HD hoist with direct-mount hydraulics and air shift controls, plus a dump angle limit switch and a backup alarm/body-raised indicator kit. The 1/2 cab shield is 10 ga with a tarp tie-down. The Mountain electric tarp assembly uses a vinyl tarp with flaps (14'–17'). The body also includes a 2" x 1/4" flatbar tandem lower rail, an 18" grip-strut step under the driver-side front rubrail, a flatbar step at the front driver side, and two flatbar steps inside the body on the driver side, turned on edge. Other features include wood side boards (8" side board height, 6" mid board pocket height) painted to match the body, an LED light kit with harness, a temperature probe hole, front anti-sail and rear standard mud flaps, and a DuraClass Black finish. The unit has no hitch. Chassis-side equipment includes a steel 3-piece aero bumper in bright finish with bumper-mounted daytime running lights, and composite fender-mounted headlights with integral DRL/park, turn and side marker lamps. It also has five aero LED marker lights in chrome housings, LED stop/turn/tail/backup lamps bracket-mounted LH/RH at the end of frame on a moveable crossmember, and switch and wiring for an F/O beacon/strobe. Fuel is carried in a polished D-shaped 100-gallon aluminum tank under the LH cab with a polished non-slip step, polished tank straps and a fuel cooler. A large DEF tank sits LH back of cab with a polished stainless cover. The RH side has a polished aluminum space-saver battery box with side access and a rubber battery pad, plus a complete aftertreatment cab entry with an aluminum non-slip step. The cab, hood, fenders and roof are finished in white Axalta two-stage paint over a black frame.
