Seller's description
2021 Chevrolet Silverado 3500HD Dually Duramax Flatbed – Mechanic Special Price: $20,500 Mileage: 141,500 miles VIN: 1GB4YSEY1MF109806 Location: Lakeland, Florida Title: Clean Selling a 2021 Chevrolet Silverado 3500HD dually with the 6.6L Duramax turbo diesel and a heavy-duty aluminum flatbed. This is a solid late-model work truck that has been serviced regularly, but the transmission has failed and will need to be rebuilt or replaced. Because of the transmission issue, the truck is being sold well below the price of a comparable running Silverado 3500HD. It could be a worthwhile project for a diesel shop, fleet operator, mechanic, or buyer with access to a replacement transmission. The aluminum flatbed is lightweight, practical, and resistant to rust. It gives the truck a useful setup for construction, welding, equipment hauling, farm work, hotshot support, or a commercial service-truck build. The following diagnostic codes are currently present: P129F – Fuel Pump Driver Control Module / requested fuel flow incomplete P22FP – NOx sensor performance The truck cannot be driven away and must be picked up with a suitable heavy-duty trailer, tow truck, or winch-equipped transport capable of handling a one-ton dually flatbed. Sold strictly as-is and where-is with the known mechanical problems disclosed above. Payment accepted by cash, cashier’s check, or bank wire transfer. Serious buyers are welcome to arrange an inspection before purchase.
