Another great work truck. This has the monstrous 8.1 liter v8! It is a gasoline engine with TONS of power. It already has a 5th wheel hookup and also a regular towing package, flatbed with gated sides so you don't even have to take the trailer if you don't need it. It's also a dually so you won't have any trouble towing your trailer! Under 80,000 miles! This truck is just broke in and ready for the long haul!
