Brand new, never-titled 2026 Western Star 49X heavy-duty vocational chassis, sitting on our lot ready to be built to suit. Whether you need a tri-axle dump, a hooklift, a roll-off, a heavy service truck, a water tanker, a plow chassis, or anything else — this is the right bones to start with, and we're the right shop to finish it. We're Smith Truck Body, a vocational truck upfitter in Central Michigan. Buy the chassis as-is and take it to your own builder, or let us spec the body and upfit you a turnkey truck. We do hooklifts, roll-offs, dumps, service bodies, and everything in between, in-house.
