From the F150 Ford Technical page. I only see one that says over 3K payload. Most are much less. Notes are:
1Heavy-Duty Payload Package only. 2TREMOR Package only. 3Max. Trailer Tow Package only. 4SVT RAPTOR only. 5Limited only.
6Requires Heavy-Duty Payload Package and Max. Trailer Tow Package.
As I found with my GMC Sierra
1500 the weights in the brochure were, shall we say, optimistic. My guess is they are all based on the base truck. Start adding the doodads like larger tires, trim packages, etc. you may quickly see, as in my case, 300# disappear rapidly. Not sure if the published weights include a full tank of gas
My truck on the scales, full of gas, nothing in the bed, no tow equipment weighs 5730# against 7200# GVWR. So 1470# available payload. Specs from the brochure for a CrewCab 4x4, 5.3L, say 1957#.
All of those options appear to have taken their toll.
Interesting perspective in this article
