I verified via scale that the actual weight is very close to GVWR minus payload capacity. I didn't believe it at first since there were a few hundred extra pounds on the scale that I couldn't account for, but when I added 200# for myself, and a couple hundred for tonneau cover, bedliner, misc. glove box contents, etc. it seemed to account for the difference. It's very easy to underestimate the impact of added misc. load we all seem to add.

Starting to wonder if payload already factors in 150# driver like tow rating does (even though the tow rating specifically states that it includes the driver but there is no mention anywhere that payload includes the driver).

Never been to a CAT scale but it looks like there is one at a truck stop about 12 miles from my house, maybe i'll try to get over there one day...

I don't think the driver is factored in for payload capacity - just for towing capacity.

The federal guidlines in the law say it should be, but ford does not indicate that it is. In fact the fed guidlines suggest factoring in 150lbs for each seating position. Found this by looking more into what I found weight wise when I ran my numbers.

There are no federal guidelines for this, so don't know what you were looking at, unless you are thinking of J2807.

• For light-duty full-size pickups (GVWR < 8,500 lbs.), SAE J2807 assumes that the tow vehicle includes any options with higher than 33 percent penetration;
• It assumes there is both a driver and passenger in the vehicle, each weighing 150 pounds;
• It assumes that tow vehicles also include up to 70 pounds of aftermarket hitch equipment (where applicable); and
• For conventional trailer towing, SAE J2807 assumes that 10 percent of the trailer weight is on the tongue.

So, the towing standard from SAE, J2807, does point out 300# for people, plus 70# for the hitch itself, however, this has nothing to do with Payload.



To answer the posted question, what does Payload include?


Answer is, https://www.fleet.ford.com/truckbbas...load_SB_v5.pdf

The base curb weight only includes the fluids. Does not include people, nor options. The payload sticker is calculated based on the base curb weight, plus any factory added options.

That is actually a pretty handy PDF to have around. It list the factory weight of all options, including tires and wheels. For example, Navigation and sunroof add 72 pounds to the truck.

Yes there are guidlines actually a law part of the federal code. I will look up again later, it governs how manufacturers set payload and other ratings. The PDF you show is the sourcebook, it where I got the option weights of my trucks options as I stated in the first post. Still doesnt explain why my truck weighs what it does. The scale slip does not lie, it even shows the added weight on rear axle as being about what I calculated over base numbers.

5.0GN tow

The section determines how GVWR is estanlished its 49 cfr section 567.4, G3 I think to be exact. It says GVWR can not be less than curb weight plus 150lb per seating position, plus cargo weight. There is section in 471 of 49cfr that also deals with curb weight, and says it must include the optional heaviest engine.

When you find it, post it, will be interesting to see.

Right, and based on everything I've found from Ford, you are correct but it seems like a few people who have weighed their 2015+ trucks have found that they weigh less then GVWR-Payload which is what makes me wonder.
