The little yellow sticker on the door pillar shows the payload capacity. I know it is the GVWR minus the actual weight of the vehicle but does that include a full tank of fuel or is it weighed with whatever fuel is in it as it goes out the door and you have to subtract the weight of a full tank? The reason I'm asking is I weighed my dually this morning and it came in at a total of 9600 pounds, which leaves 4400 pounds of payload capacity left (14,000 minus 9600). That weight includes me at about 170, about 30 pounds of groceries, a 180 pound fifth wheel hitch and a full tank of 48 gallons plus a full auxiliary tank of about 27 gallons. If I subtract all that weight from the 5247 yellow sticker capacity it comes out to about 4350 pounds. This leads me to believe the yellow sticker does not include fuel.

But, when I look in the owner's manual under load carrying it explains in detail how to determine if you are within the capacity of the truck by adding the weight of any cargo, passengers and what appears to a be trailer hooked up, hard to tell from the picture. Anyway, subtracting the weight of fuel is never mentioned but using my weights it doesn't compute if I don't subtract the 48 gallons times 7 pounds for the full tank.

 

Fuel weight counts against the payload numbers, needs to be subtracted just like any other cargo or passengers.

 

I would think that curb weight would be the starting point, that would include all fluids.

 

Yes, your cargo capacity has already taken into account a full tank of fuel.

From the 2017 Towing Guide:

 

Thanks, Jim. Never thought to look there. Now it makes me wonder where that extra weight is. If 5247 is my starting point with a full tank I can come up with maybe 600 pounds of stuff and me. It should leave me with 4600 to 4700, not 4400. I'm certainly not going to worry about it as I have way more than I need even with the lower figure. Maybe I have too much air in the tires.

The reason this came up is because I was looking at the increased weight ratings for the new GM hd's in the single rear wheel versions. If the new Fords do the same I can possibly do without the dually as it really borderline that I need it. Just me, but I just don't like driving a dually for my daily driver and pulling my bass boat, which it does a whole lot more than pulling our fifth wheel. I would much prefer the smaller footprint and turning radius of a single rear wheel.

 

Good to know, I always assumed fuel counted against the payload. That nets me another 200-ish lbs for other stuff.

 

My registration lists an unladen weight, I dont know where they get the number from, but its 235lb. lighter than what I come up with using the gvwr - payload number. I have not weighed it, although I'm curious now.

 

I weighed the truck today so I can next weigh it with the fifth wheel and figure out how much hitch weight I have. When Ford releases their capacities for the 2020's I will see how they stack up against the GM's. Probably shouldn't say this on a Ford site but I actually have no preference between the two. I've had both and they've all been good. I do know the new GM 3500 single rear wheel crewcab diesel is rated at 4185 payload but a Denali will ding that some. Most Platinum or KR F350 singe rear wheel diesel's I looked at have between 3200 and 3300 payload. I need another 300 to 400 pounds to have a little cushion. The GM is also rated for a 21,300 pound fifth wheel and mine is around 15,500 so that will be good on the Ford also I'm sure. Whether or not Ford changes their weight figures remains to be seen but I bet they do something to keep up with GM.

 

I think you misunderstood what was said. Fuel does count against payload, along with a 150lb driver. Anything above that affects your payload capacity.

 

He was under the impression that the fuel weight gets subtracted from the payload rating on the yellow sticker, like cargo and passengers, but it does not.

 

Didn't see anything on a 150 pound driver in the above info. Is that in the manual somewhere?

 

The 150 lb driver is used in calculating the SAE tow/GCWR ratings. Not curb weight.

 

Payload rating does not include an allotment for a driver. All occupants (including driver) will count against the payload rating on your door jamb sticker.

 

How is your dually only rated for 15,500?

IMO, airbags and good tires on a SRW and you'd be just fine...

 

Bad sentence structure. I meant my fifth wheel has a total weight of 15,500. My hitch weight is north of 3000 so adding in my extra fuel, my wife and I, our overweight Boston Terrier, the fifth wheel hitch and some tools I exceed the payload capacity of most single rear wheel Platinum or King Ranch F350 diesels. I could get closer with a model with less options but we do prefer the niceties of the loaded models for our travels which can and usually does cover a lot of miles.
