Payload capacity: Includes 150 lb driver? Fuel? Or neither?

My 2000 and 05 GM's, the door sticker less gvwr equals this sticker. The glove box sticker, camper load Plus 900 for 05 de cc, and +450 for rag cab 2000 equals door sticker payload. Ive sold the 05. I'm an hour and a ferry.ride across Puget sound to the 2000. To verify numbers. But payload sticker is 38cd lbs. 8600 less this is 4800, which is what all other stuff says truck should weigh, along with me weighing it as such.
05 was base at at 7300, payload sticker was 4100 totalling 11400 gvwr of truck.
