GVWR or GAWR (front + rear)

If I add up the front GAWR (4,800 lb) and the rear GAWR (6,340 lb) I get 11,140 lb. The sticker says my GVWR is 10,000 because I asked it to (special package).

My payload is 3,105 lb which leads me to believe the curb weight of the truck is 6,895 lb.

Does this mean I really have a Payload of 4,245 lb?

IYour payload is what it states on your door sticker and not what you get adding up the front and rear axle gawr’s and then subtracting your curb weight. When you load your truck, who knows what you will be doing, so the gawr ratings are there, so you do not overload an axle, as you’re not always going to evenly distribute the weight from your load. For example, my Expedition had a payload capacity of approximately 1,600 lbs and could handle a trailer tongue weight of 920 lbs, however if I did put that much weight on the back end, my back axle would be overloaded according to its gawr and thus why I needed a weight distribution hitch to move some of that weight to the front axle.

There are cases where Ford has lowered what these trucks can actually handle, the F450 is a good example. That truck could handle a lot more than what the stickers state, but for various reasons Ford has kept it in a lower weight class. So legally you cannot exceed your gvwr rating.

Hope this makes sense.

Your rated payload is 3105. If you have an F250, the 10k GVWR is correct for the truck. If you have an F350 with the 10k GVWR package, I think you have a 11,500 GVWR designed truck with a 10k rating. Keep in mind that your rear tire pressure is for your rated capacity. (I.e. if you have an F350 and are going to treat it like a 11,500 GVWR truck, you'll need 80 PSI in the rear tires, not 65.)

stay within the GAWR of each axle and the tire ratings, whichever is LESS and you are fine. The 10K number is for a weight class for the registration purposes.

It's hard to say when this approach works. I think the max axle ratings for an F350 SRW are 7230# and 6000#. That yields 13,230#, which is 1730# over the GVWR. Perhaps this works OK for weight class limited trucks (F250, F350 DRW, and F450), but I don't think this gives a safe answer for the F350 SRW. It also assumes that your truck is balanced just right.

I think it's probably OK in this case, but I didn't want folks to think this approach always works.

Ford’s standard guidance is to go by the lowest-rated components in an axle assembly: axle, springs, wheels, or tires. For example, the springs are the the lowest-rated components in our truck’s front axle assembly, and they set the 4550 lbs. front GAWR. On the other hand, the tires are the lowest-rated components on the rear axle, and they set the 6780 lbs. rear GAWR.

According to his profile, the OP’s truck is a 2018 F250.
