2026 Peterbilt 537 4x2 IMT DOM3S5 Service Truck w/ 12600 Crane

Owning this truck means one unit does the work that often takes a crane truck and a separate service truck. The IMT 12600-32 crane on a Dominator III S5 body lets your techs lift heavy components and carry their tools and parts to the job, so you avoid hiring or dispatching a second machine for most swaps. The 4x2 layout, with a 13,000 lb front axle and a 21,000 lb rear, gives the crane and body a solid platform while keeping the truck easier to maneuver and park than a tandem-axle chassis. That helps in tight yards, plant sites, and congested job sites. Air disc brakes give consistent stopping power with the crane and a loaded body on board, which adds confidence for drivers and works in your favor when it’s time to maintain the truck. The PACCAR PX-9 at 360 hp with an Allison 3000 RDS 6-speed automatic is a familiar, easy-to-drive powertrain, so more of your drivers can run it and your shop likely already knows how to service it. For fleets that want a crane-equipped service truck that is practical to drive and keep running, this one is a straightforward investment.
