The Peterbilt 348 is Peterbilt’s medium-duty vocational truck, built until the 548 replaced it, and it shows up as a dump, roll-off, box truck, tow truck or local tractor. Many run the PACCAR PX-7, a 6.7-liter engine built by Cummins, which keeps parts and service easy to find. It pairs Peterbilt build quality with a size that suits local delivery and construction work. Every truck we sell gets a third-party DOT inspection and third-party service before it’s listed, and we offer financing and delivery. Call or text 616-600-2682.
