I've seen this discussion time and again without it ever being resolved.

Buck, according to the Ford rep I talked to, they said the payload and the towing account for an 150# driver. I made sure I specifically asked about it as I knew I would be close with my ratings when I get ready to hook up my 5th wheel. Still waiting on my truck to get here, Grrrrr!!!!

JohnB, be sure you check out the weights of the 5th wheel hitch you plan on using. There is quite a bit of difference between brands. The Reese 16R I bought to go in the new truck weighs only 135# with the slider where as the B&W I have in my F-250 weighs 280# and it's the same one that fits the F-150.

I have weighed my truck and can confirm there appears to be no allowance for driver weight in the payload rating. My trucks gvwr is 7350 lbs and the payload sticker says 1420 lbs. Weight of empty truck with no one in it but with a full tank of fuel was 5930 lbs.

atvtinker, thanks for the warning on the hitch - definitely will look into this.

As for the issue of whether the driver's weight is accounted for as 150lb or not - looks like we have two strongly different sides here... How could that be?

Ken, how old is your truck?

Yes, I'm sure, due to a few reasons. Several have weighed their trucks and seems to be no allowance for driver. Also, the owner's manual says so. There is an example calculation and they show subtracting the weight of driver AND passengers from the payload sticker value in order to find the capacity for junk and/or trailer tongue weight.

Base curb weight = wet weight, including full tank, base vehicle with no options(advertised value)
Vehicle curb weight = base curb weight plus options
Payload sticker = GVWR - vehicle curb weight

I see. That's unfortunate but it's a reality.

What about the weight of liquid? 36g of gas is a lot of fuel in weight...

Full tank is accounted for so if you drive around with 1/2 tank or less, you gain 100 lb payload

trailers are weighed "wet" trucks are weighed "dry" for base weight measurements.

The GVWR will be the same no matter what. Weigh the truck, deduct from the GVWR and thats the payload.

If you are 100-150lbs from deciding on a trailer, its too heavy

The gross vehicle weight rating (GVWR), or gross vehicle mass (GVM) is the maximum operating weight/mass of a vehicle as specified by the manufacturer including the vehicle's chassis, body, engine, engine fluids, fuel, accessories, driver, passengers and cargo but excluding that of any trailers.

The weight of a vehicle is influenced by passengers, cargo, even fuel level, so a number of terms are used to express the weight of a vehicle in a designated state. Gross combined weight rating (GCWR) refers to the total mass of a vehicle, including all trailers.

GVWR and GCWR both describe a vehicle that is in operation and are used to specify weight limitations and restrictions.
Curb weight describes a vehicle which is "parked at the curb" and excludes the weight of any occupants or cargo.
Dry weight further excludes the weight of all consumables, such as fuel and oils.
Gross trailer weight rating specifies the maximum weight of a trailer
Gross axle weight rating specifies the maximum weight on any particular axle.

Getting back to the OP's fifth wheel, think I've heard that you'll overload the rear axle weight rating (rear GAWR) before the truck's payload, even with the HD Payload option. Is that correct?

With a bumper pull you can move some of that weight off with the WDH, but run into hitch ratings as mentioned earlier.

My truck is 6029 lb. From typical weight distributions I've seen, it probably has about 2800 on the rear axle. The axle rating is 4800lb so my rear axle has 2000lb remaining and my payload is 2171. With me in the driver seat and 2000lb in the box, the rear axle would be at ~4850 lb and the truck at 8200GVWR. The rear would be slightly over because part of my weight is supported by it in addition to the 2000 box load.

Since my 5th setup only puts about 1700 (with hitch) directly over the rear axle and the rest of the weight (passengers) is split with the front axle, there's really no way to overload the rear axle while staying under GVWR.

A 2wd HD with 4800 RAWR and any of the Max Tow models with 4050 RAWR are easier to max out the rear axle before hitting GVWR.
