On my new truck, GCWR = 14,000 pounds, minus wet and loaded truck weight of 6,550 pounds = tow rating per your formula of 7,450 pounds. But my wet and loaded TT weighing only 4,870 pounds put me over the GVWR of the truck by 100 pounds. So the manufacturer's tow rating of 8,200 pounds was overstated, and your tow rating of 7,450 pounds is overstated, because neither considered the GVWR and resulting limitation of hitch weight. The truck's GVWR is 7,100 pounds, and it weighs 6,550 wet and loaded before tying on the trailer, so my max hitch weight is 550 pounds without being overloaded. But the actual tongue weight on that trailer was 650 pounds on that trip, so I was overloaded with a trailer that grossed only 4,870 pounds (4220 trailer axle weight per the CAT scale plus 650 hitch weight per the Sherline tongue weight scale).

Back up 10 years to my F-250 diesel-powered hot-rod towing machine. GCWR 20,000 pounds, GVWR 8,800 pounds. Ford's tow rating of over 13,000 pounds. Wet and loaded tow vehicle weight was 8,000 pounds. So your formula gives me 12,000 pounds tow rating. But wet and loaded trailer weight was 8,000 pounds, and my max hitch weight was 800 pounds without being overloaded. Easy math shows that when on the road with that 5er (hitch weight about 16 percent of loaded trailer weight) I was overloaded by several hundred pounds. So I'm really glad I didn't use you formula and wind up extremely overloaded with a 5er that grossed 12,000 pounds.
We are beating a dead horse here. He asked for tow rating, that's what I gave him. Truck GVWR, cargo capacity, pin weight, etc is a related but slightly different subject...and the other part of the equation.

Ha! Welcome to the Internet. And we wonder why a true democracy would not function in government!
