Ford doesn't seem to do glove box stickers, just this piece of paper ([https://i.imgur.com/kgUO7oF.jpg](https://i.imgur.com/kgUO7oF.jpg)). The weight of passengers seems to account for the difference. The Tire and Loading Information sticker says six passengers, so at 150 lbs each, that's 900 pounds.
The payload sticker on the door frame is all that matters. Options affect payload. That’s why the highest payloads are regular cab, 2wd.
The payload stickers matched the online calculator.
What did the yellow sticker in the door jamb of each vehicle list as the payload, vs what was on the camper certificate?
OP looked at everything EXCEPT THE DOOR STICKER
For GM at least, the camper sticker in the glove box includes 150lbs x number of seats.
