Forget about that 9300 lb towing capacity. It was calculated without passengers, cargo, or aftermarket accessories. In theory, the truck could pull that weight, if it is empty as it was at the factory, and the driver is alone with no cargo. As any of these things get added, the actual tow rating is going down, pound for pound.
Besides the ratings you have listed, your vehicle also has a max cargo / occupant rating (AKA payload). Look for a loading sticker on your drivers door post. This is what it is rated to carry (GVWR minus empty factory weight). Payload gets eaten up by everything in or on the truck, that wasn't there when the truck left the factory. It includes people, pets, cargo, accessories (undercoating, step bars, bed liners, bed caps / covers, even floor mats), weight distributing hitch, and trailer tongue (hitch) weight. Normally, you will run out of payload, before you get close to that mythical tow capacity.
Here's a link to a calculator that may help you find a good trailer weight.
Average camping load (dishes, pots and pans, bedding, camping gear, tools, groceries, water, etc) is 800 to 1000 lbs. When shopping for trailers, keep this in mind.
Average trailer tongue weight is 12.5 percent of loaded trailer weight, and, it is not a constant number. It goes up and down during every trip. Water and groceries get used up and holding tanks get filled and emptied. Depending on location (in relation to the trailer axles) of holding tanks, they can have a large impact on tongue weight. Mine can fluctuate by as much as 200 lbs.
Average weight of a distributing hitch is 90 lbs.
The closer you get to your max weight, the more the tow vehicle will struggle, and the more unpleasant your towing experience will be. Leave yourself some room for unplanned cargo and guests.
