The versatility of the new Model 537 and Model 548 is built upon a new customizable chassis and multiplex electrical architecture. The trucks deliver seamless body builder integration, allowing customers complete customization to spec their truck to fit their needs.
There are two hood options, a vocational 3-piece Metton hood featuring a stationary grille with full through rail, and a three-piece SMC aero hood for maximum visibility. Both hood options can use a variety of vocational and FEPTO bumpers to fit different applications. The bumper is front mounted to the chassis with a drop-and-go feature for self-locating. Bumper options include two finishes (chrome or painted), three bumper light mounted options (headlight, daytime running lights or fog), two radar options, two tow options (two tow loops or center tow), and two license plate mounting locations (center or offset).
Wide or standard track axles feature superior wheel cut angles for a shorter turning radius and mono-leaf or taper-leaf front springs are rated from 8,000 up to 20,000 lb. The rear suspension is available with a taper-leaf or air leaf suspension rated from 12,500 to 40,000 lb. depending on a single or tandem drive configuration. The AWD option features a new offset bowl design to offer the lowest possible cab height.
The new 2.1m cab is 8 in. wider inside than the previous generation cab and has room for 3 adults to seat comfortably. Stair-style steps and knurled grab handles make getting into the trucks easy. The best-in-class interior features 4.6 cu.-ft. of storage space, 3 cup holders and a dash layout with available space for optional gauges, switches and ram mounts.
An new instrument cluster, featuring an analog speedo and tachometer with a high-resolution, 7-in. digital display relays key information at a glance. Drivers are able to toggle through menu cards on the digital display utilizing the new multi-function steering wheel and the display navigation knob. The digital display is deeply integrated into the electronics of the truck with key information like system check, trip summary, PTO functions, ADAS and TPMS all clearly displayed through the menu cards.
