Used 2020 Peterbilt Rollback Trucks For Sale in Florida

The most common setup is a Cummins 6.7L engine, often rated around 260 hp, paired with an Allison automatic such as the 2200RDS. That combination is popular because it is easy to train drivers on, works well in stop-and-go towing service, and has a broad service network. On heavier rollback builds, buyers may also encounter larger Peterbilt chassis with PX-9 or ISL9-class power and Allison 3000 series transmissions, but the 2020 337 is the more typical fit for light-duty carrier work.

Most buyers should verify deck length, deck width, bed material, winch rating, and wheel-lift capacity before comparing cosmetics. A common 2020 configuration is a 20-foot by 102-inch low-profile steel bed with removable rails, an 8,000-lb Ramsey-style winch, and a 3,500-lb wheel lift. Those specs are well suited for passenger vehicles, pickups, and light commercial units. If the work mix includes lower-clearance vehicles, XLP or extra-low-profile decks can be a major advantage because they reduce loading angle and help prevent front-end damage.

It can be a very strong fit for Florida operators because the 26,000-GVWR Peterbilt 337 carrier is maneuverable in urban traffic, parking lots, dealership lanes, and highway service environments. In a warm, humid market, buyers should pay close attention to corrosion on the carrier subframe, hydraulic lines, bed crossmembers, wheel-lift components, and electrical connections for the light bar and work lights. Air conditioning performance, tire condition, and proper operation of the PTO and hydraulic system also matter because these trucks tend to idle, cycle often, and work in high-heat conditions.

The best trucks usually stand out in the details of the upfit and how well the truck matches the intended route work. Air brakes and air ride suspension improve control and driver comfort. Aluminum wheels, heated power mirrors, and low-profile 22.5 tires are common convenience and appearance upgrades. On the body side, removable rails, dual toolboxes, LED work lighting, remote free spool, a side recovery system, and a cleanly installed PTO setup add real value. Service records for the chassis and hydraulic system often matter more than trim level because downtime in towing service is expensive.

Start with the carrier and hydraulic system, because that is where tow-truck revenue is made. Check bed slide function, tilt operation, winch pull, cable or rope condition, wheel-lift wear, and PTO engagement. Then inspect the chassis for engine fault history, transmission shift quality, brake condition, suspension wear, and signs of frame modification or repair. On a Peterbilt 337, it is also worth checking cab electrical items, switches, lighting circuits, and any evidence of hard commercial use around the deck pivot points and rear structure. A rollback can look clean and still need expensive hydraulic or body work, so a functional inspection is just as important as a road test.
