Weight cops are out in full force I see.....and one ambulance chaser to boot!
OP, you got about a 9 ton 5ver to tow. That's a lot for a srw truck, imo and I do some pretty silly stuff with trucks from time to time, lol.
That said, you've got a rear axle good for 10klbs, same frame/ brakes as a dually and all the power in the world. You'll need suspension help for the pin weight and I'd have some tires that were good for 4klbs or close to it and let er rip.
Disclaimer: "You" may not be comfortable with it though. Simply by way of asking the question alludes that you have little/no experince towing something this heavy.
