Here are a few the items that will contribute to both. Keep in mind, when these ratings are made for the door sticker, the are made using a stock configuration.
1. Axle ratio
2. Engine
3. Additional oil and transmission cooling
4. Springs
5. Differential selection
6. bed length
7. Cab over frame length
8. Rim size and style
9. tire size, style, and load rating
10. Brake capabilities
Your payload rating will fluctuate per model/ trim against the curb weight. Essentially- GVWR is the absolute max, take away your curb weight, this is the allowable payload maximum no matter what (which includes the tongue weight of your trailer- lots of people forget that one). The reason yours and your friends differs is down to the curb weight and options installed. Put a winch on your truck, your payload technically drops by that much (although I don't know of a single person that worries about that one). So, the FX4 will have 373 gears which is in his favor, but his truck is likely lighter on the curb weight against your platinum. He has plastic bumpers for example. Yours are steel. Someone jump in to correct me if I am wrong, but I believe the FX4 also has a few minor differences in the suspension. Little things like that can add up quick. The GVWR ratings seem to be an arbitrary number that has some movement built into it for upgraded components. To be honest, there are a whole myriad of things that can change that. 18" vs 20" rims, so on and so on.
This should not be taken as biblical though- this is how my insurance broker that I married explained it- but then again, I have been known to be kind of dumb sometimes.

The most often overlooked answer to this question is fuel tank size, 26 v 36 gallons... At 10 pounds per gallon (estimated) this alone contributes to 100 pounds in weight difference. Both vehicles are calculated using curb weight which changes by options, as metioned earlier.

Water weighs 8.3lbs per gallon.
Gasoline weighs 6.2lbs per gallon.

Payload = GVWR (Gross Vehicl Weight Rating) - Actual Weight of Vehicle
The payload can be found on the side of the door. If a truck has a 7100 GVWR and a higher payload, then it is because it is lighter than the truck with a GVWR of 7350.
5 liter weights more, Platinum has more options that adds weight. This is why there is a disparity in payloads....

Bottom line is this.
You can put heavy ply tires and add as many extra springs and or air bags to carry as big a load as you want... but when you are in an accident you will be charged and be liable for being over the GVWR of your vehicle.
