You all need to look at this a dfferent way.
There is a gross combined weight listing for every truck combination.
You have to weigh the truck then add the driver weight and any other weight that will be included.
Subtract this from the gross combined weight allowed and that is the trailer weight that is allowed with considerations for tire size.
The weight for loading the truck only is the total of the gross weight rating on the sticker minus the weight of the truck and any passengers and gear.
My 02 super crew weighs 5400 lbs with some gas in the tank.
The gross combined weight allowed is 11,600 lbs for towing and based on the engine size, the trans, gear ratio, tire size and being a 4x4..
If you allow, for example, 4 in the cab at a total of 600 lbs, then 5400 + 600 = 6000 lbs.
11,600 - 6000 = an allowed trailer weight of 5600 lbs to meet the gross combined weight factory rating.
With only a 200 lb driver, add 400 to the trailer weight and it goes to 6000 lbs.
So your legal trailer weights per Ford vary with the truck loading.
State law may modify this in some places but Fords reccomendations are based on the trucks abilty to brake, trans durabilty for reasonable life, tire loading, axle bearing capacity etc.
If for example you were to be stopped and weighed, the station may have all the info on your model and would handle the total weight measured accordingly
