As I understand it, I can tow 12,000 plus my truck of 6,000, according to my owners manual, that nets me a GCVW of 18,000lbs. I have a GVWR of 10,000lbs, the S&S loaded and ready to camp and truck come in at 10,350lbs full of fuel, water, gear, food, and breathing entities. So that leaves me the ability to tow a 7,650lb trailer behind me. I have 1,000lbs left on my rear axle, and 800lbs left on my front at 10,350lbs. Since I flat tow the Scout 90% of the time, I have no tongue weight and it runs about 3,300-4,000lbs depending on what I load in it.
