A friend has this 2012 F450 XL chassis cab 4x4 with 9ft flatbed for sale. It only has 16,000 miles on it and is like new. V10 auto with 4.88 rear axle. It has both a gooseneck ball and a 22,000 lb fifth wheel hitch. The fifth wheel hitch is negotiable. Lots of custom accessories like the wheel covers, running boards and tool boxes. He used it to pull his 33 ft triple axle fifth wheel travel trailer when he worked. But has not been able to work and is now retired. Trailer was exceptionally heavy as it was loaded with everything they needed to live in while working around the country and is already sold. 8.2 MPG when towing the heavy trailer.
