Because the 9,300 "tow rating" limit is based on the GCWR of the truck, and the 7,350 is the GVWR of the truck. Different weight ratings. You're mixing apples and oranges. As noted in my previous post you probably shouldn't try to tow a TT that weighs more than about 6,000 pounds if you don't want to be overloaded.
Your truck has several weight ratings: GVWR, GCWR, front and rear GAWR, the weight ratings of your tires and wheels, receiver hitch, truck's frame, axles (which is different than GAWR) and other components such as springs and shocks.
Ford says you should NEVER
of the weight ratings.
Ford also includes some info that are not actual weight ratings, but fuzzy math numbers of tow rating and payload rating. The fuzzy math is to use unrealistic weights to derive those numbers. The tow rating of 9,300 pounds is the GCWR of the truck minus the shipping weight of that truck with no options and absolutely nothing in the truck but a skinny driver. But that number is misleading because nobody drives a truck with no options and nothing in the truck. Thus, that 9,300 number quickly shrinks to around 6,000 pounds when you load the truck with normal options, people and other cargo.
The gross vehicle weight rating (GVWR) of the truck is the maximum weight your truck is designed to carry on the truck tires, including people, pets, tools, jack(s), trailer hitch weight, full tank of fuel, and any other cargo such as campfire wood, animal or pet feed, cooler, water jugs, whatever.
GVWR is the most likely limiter of how much trailer you can tow without being overloaded (exceeding the GVWR of the tow vehicle). Your GVWR is 7,350, so your wet and loaded truck, including trailer hitch weight, should never weigh more than 7,350 pounds on the two truck axles. The only connection between the truck's GVWR and the weight of any trailer you can tow is the hitch weight of that trailer.
The gross combined weight rating (GCWR) of your truck is the maximum combined weight of your truck and trailer, and it tells you the maximum weight your truck can pull
without overheating anything in the drivetrain, and without being the slowpoke holding up traffic on hills and mountain passes. But the GCWR ignores the effect of the cargo in the truck and the hitch weight of that trailer on the load-carrying capacity of your truck. Most normally-loaded trucks can pull
a lot heavier trailer than they can haul the hitch weight of that trailer without being overloaded.
For example, my F-150 can pull a trailer that grosses my tow rating of 8,400 pounds over interstate mountain passes in the Rockies with no sweat. But it's overloaded over the GVWR of my F-150 with my TT that grosses only 4,780 pounds. So your Ford tow rating of 9,300 shrinks to a real-world tow rating around 6,000 pounds, and my Ford tow rating of 8,400 pounds shrinks to a real-world tow rating around 4,700 pounds.
