F150 Heavy Duty Payload Capabilities

FernieHawk · May 27, 2013

So I posted some info on ‘Rowdy’s’ thread https://www.snowandmud.com/tow-vehicles-rvs-trailers-accessories-them-77/diesel-vs-gas-79564.html

My comment in that thread stated I had just purchased a 2011 F150 4x4 Regular Cab with a 5.0 liter, 8’ bed and the Heavy Duty Payload and towing package. I also stated I was planning to put a Truck Boss deck on my truck and carry two sleds legally.

A couple of people seemed to think my comment didn’t have much merit, so instead of high jacking Rowdy’s thread, I started a new one…what the hell, lets see what people think.

The Specs on the truck are as follows:

GVWR = 8,200 lbs
Front GAWR = 4,050 lbs
Rear GAWR = 4,800 lbs
Payload = 2,708 lbs

The Heavy Duty Payload and towing equipment on this truck include: 50% thicker frame rails; 17" 7-lug aluminum wheels; LT245/75R17E BSW all-terrain tires; Heavy-duty shock absorbers; upgraded springs and radiator; auxiliary transmission oil cooler; rear axle with 9.75" gear set; Select Shift Automatic Transmission with a 3.73 limited-slip gear ratio.

I weighed my truck today on a BC government certified scale and this is what the numbers came out to with a full tank of fuel (225 lbs for 136 liters) and myself at the wheel (190 lbs).

Total truck weight = 5,600 lbs…I still have 2,600 lbs to max GVWR.
Front axle weight = 3,260 lbs…I still have up to 790 lbs available for the front.
Rear axle weight = 2,340 lbs…I still have up to 2,460 lbs available for the rear.

The additional payload to be added is one person @ 200 lbs, one Truck Boss deck @ 350 lbs and two sleds totaling 1,100 lbs. This all adds up to an additional 1,650 lbs of payload and since I have 2,600 available it should mean I have 950 lbs wiggle room for extra fuel, gear, beer and tools.

I’m not sure how the additional weight will be spread out over the front and rear axles, but I’m thinking I should be good to go…I have a thick skin, so all you ¾ and 1 ton guys can flame away if you like. Its not my first truck and I don’t play favorites…I’ve owned a 1 ton, a ¾ ton, a ½ ton and yes, even a ¼ ton…it did have a 4.0 liter in it at least.:d

Room for lots of beer !

Just curious but have you looked at other sled decks besides marathon. ? I have nothing against them but they are pricey

Wow my 2010 ext cab .4x4 with 7700# gvwr and towing package only has a 1850# payload. That's nuts for a .1/2 ton

I used to own a Marathon Classic and really like the Truck Boss. I plan on getting the slide out storage bin because I need secure/dry/clean storage as I only have a Regular Cab, the Truck Boss provides a water and dust proof seal around the whole perimeter and you can also seal the tailgate sides and bottom. I also like all the capture channels for accessories. Definitely other good decks out there, but the Truck Boss has some unique features and are 100% aluminum (except some hardware). I'm going to hook the tailgate lock up so it activates with the power door locks.

Ya... the payload surprised me. I wasn’t looking for this specific vehicle when I was looking for a new truck...I stumbled upon it while on Kijiji and decided to check out the specs. I thought to myself...hmmm, I wonder if this truck will work out to carry 2 sleds.

S&M will never be the same. Monumental thread right here. From this time forward no one can give obnoxious responses when someone mentions a deck on a half ton.

I'm not trying to start a F-150 HD vs Superduty war, but I just found some interesting specs on the brakes for the 2011 F-150 and the 2011 F-250 and F-350 Superduty trucks. Someone mentioned brakes as a concern in Rowdy's thread, so I thought I would add the info...

All of the F-150 have larger rotors on both front and rear.

F-150 Front = 13.8 x 1.34 in discs, dual 2.13 in pistons
F-250 and 350 Front = 13.66-inch discs

F-150 Rear = 13.7 x 0.79 in disks, single 2.00 in piston
F-250 and 350 Rear = 13.39-inch discs

The Ford spec sheets did not specify disk width or the piston sizes for the Superduty trucks.

Are there full floating axles or semi floating axles on this truck??

That is a good question and I don't know the answer, I will see if I can dig it up. It has a 7 lug Hub but I'm not sure if it is full or semi floating.

CUSO · May 27, 2013

That's the kicker.

You can beef up the frame, springs, brakes and motor, but if the axle shafts are bearing the weight, and that payload is 2 plus feet above the bed.... that's a different story than filling the box with dirt.

Are u trying to talk Ur self into it ??

The 1/2 tons might have a bigger rotor in diameter.

But not thickness and that's what takes the heat.

The rear Diffy will be a semi floater ..

No matter what the #'s say u can not have a deck , with 2 sleds and the gear that goes with on a 1/2 ton and be safe and legal.

You are the man for starting a new thread! The specs look good. I am no expert and may need a little help here. How come the GVWR at 8200 is lower than the combined Front and Rear GAWR?

GVWR = 8,200 lbs
Front GAWR = 4,050 lbs
Rear GAWR = 4,800 lbs

When all is said and done (deck installed), load two sleds, and get a buddy to go with you to the scale east of Sparwood. Check the weight on both axles and see where you are at. The thought I have is that you cannot be over the GVWR meaning that the total of the front and rear axles has to be no greater than 8200#.

Someone correct me if I am wrong.

I'd rather pack 2 sleds ,Than pull 10,200 pounds with a half ton.

Regular cab trucks always have a higher payload, especialy with the lighter gas motor, thats the reason your payload is so good, most guys own extended cabs. The worst or lowest payload trucks are actualy crew cab diesels, 3/4 or 1ton for their class. If your looking for the best possible payload your best bet is a 1ton regular cab with a gas motor. The extra weight of the bigger cab and diesel motor kills the truck for payload capability even though the motor is more then capable.

Lund · May 28, 2013

Here is another thought, i have a Superduty F350 diesel. The truck weight is nearly 8,000lbs empty (7950 i think, posted on the door) the GVWR is approx. 10,750lbs. This gives me a 2700lb payload, not that great BUT.
A class 5 drivers license has a 5,000kg restriction, translates to 11,000lbs. Anything bigger you need an endorement or different class drivers license ie. class 3.

Yes the rear axle is a semi-floater and I am aware of brake rotor thickness playing a part in heat dissipation…anyone know the thickness of the Super Duty rotors? So you don’t think the brakes on this truck are capable enough with maybe a 2,500 lb payload…what about if I want to tow a small 2000 lb boat with a 1000 lb single axle trailer with no trailer brakes, do you really think the truck is not up to the task? Really?

The truck has an electronically controlled 6-speed transmission with Tow-Haul mode and a fully manual mode. In manual mode I can put the truck in any of the six speeds and it will stay in that gear, in Auto mode I can take away any of the top 3 gears and it will turn from a six speed auto to a 3, 4 or 5 speed auto.

Even though I showed you with the numbers that the truck can legally carry two sleds, you still say it will be illegal and unsafe…could you explain with some facts?

I’m not trying to talk myself into a HD ½ ton…already completed that phase, after I did the math.

The front and rear individual axle weights always add up to more than the Gross Vehicle Weight Rating.

You are not allowed to go over any of the three ratings…its not just about the payload, its also about the placement of the payload. With the 8’ bed on this truck I can move some weight towards the back of the bed if the front axle is near capacity or conversely I could move some weight towards the front if the rear axle was near capacity. The 5-foot box on my last Super Crew did not really allow for very much weight distribution and had a really crappy payload rating.

I will definitely have the truck weighed with a full two sled load.

FernieHawk · May 28, 2013

Agree about the trailer towing.

I do not plan on pulling any heavy trailers...that is a diesels job

and I have friends with diesels...

Yup 8ft bed for the win AGAIN! Wise idea will be to have it scaled fully loaded...and return with results!
