Please answer this one for me.
2011-2016 Ford F-250 SRW crewab has an absolute maximum GVWR of 10,000. Payload stickers ranging from about 1800-2400 depending on options/features (4x4,etc.)
2011-2016 Ford F-350 SRW crewcab has a GVWR ranging from 10,700 to 11,500. Payload stickers ranging from about 2600-3400 give or take, same idea...
Both trucks are basically identical other than the sticker in the door and the badge on the side. Same axles, Same differentials, Same wheels, Same bearings, Same EVERYTHING except a 1" taller block in the rear. Same overload spring, same leafs, tires etc.
It is said that while you can never exceed the payload sticker, that the sticker isnt TRULY indicative of what Ford knows the truck can do. It simply must not exceed 10,000 because in many states that can constitute a commercial vehicle and charges for insurance and licensing can be handled differently.
So I'd say that while you should never exceed the payload sticker, in the case of the F-250, as far as *true* safety goes; the truck can handle more weight without concern. My $0.02 and I know for most other vehicles like SUV's, cars, etc. this kind of situation would not apply.
