New truck, need help with weights

I just purchased a new truck yesterday. 2014 F350 6.7, 4x2 longbed, SRW, 3:31 gears. So I would like some assistance with weights so that I'm armed with knowledge as we go shopping! What 5th TH/BH weights should I look for?

GVWR: 11500
5th towing cap: 16300
Payload: 4220
CCC: 3637
FGAWR: 5250
RGAWR: 6730
GCWR: 23500

EDIT, addedCAT SCALE:
Steer Axle: 4680
Drive Axle: 3280
Gross Weight: 7960

Little more than half full of gas. I guess I should have filled it up ๐Ÿ™‚

You done more research than I did. Sorry, this probably won't help but after seeing this guy (https://www.youtube.com/watch?v=G-BaMUA0c_E) whom I know from another forum has 3700# pin weight (has air bags) and ~18K lbs when fully loaded I figured I'd have no worries with my much lighter fiver; which turns out I don't.
Your rig can pull alot of weight but understand it comes down to what you feel safe & comfortable.

There is a lot more to towing than what can be covered in one 30-second commercial. That's why.

Ford is giving you a "best case" number because there is no way for them to predict what you are going to add to the truck, how many people you are going to haul, how much stuff you are going to load before hitching up the trailer, etc. etc..

In your case you have 3450lbs of payload capacity left on the rear axle and 570lbs of payload capacity left on the front axle.

A properly hitched 5th wheel has no effect on the front axle, so you're concentrating on the rear axle numbers.

A 5th wheel hitch sits directly over the rear axle, so that puts you down to 3200lbs. That's pretty much your limit on paper, which puts you in up to a 16,000lb (20% pin weight) 5th wheel, though a <12,800lb (25% pin weight) rig would be much more likely.

That's not what the towing specs say.

wandering1, when I started this process over a year ago I would have said the same thing. Why would Ford (or any of the manufactures) state one number vs what other would tell me.

To each is own, I've only been doing this for 2 years with a 4k hybrid, and a F150. But at the end of the day I have my family to think about and what is safe for them, and what am I comfortable pulling, driving, parking, etc.


Trucks run out of payload (carrying capacity for 5vr) long before the magical mfg. tow rating.

Don't believe them, but you will be able to tow a lot of them. Happy trails!


I'm pretty new at this, so I play dumb at Camping World! - "You have a rating of 16.3, you can tow at least that"

You have about 3500 lbs available on the RAWR. You will need to take away what your family weighs and the hitch weight before you can actually get available pin weight.

The actual axle is rated for 9750 lbs, but the wheels limit you to the 6730 lb rating. You can go to 19.5" wheels to get the full capacity of your axle, but then you bump up against the GVWR limit. People have different views about what is prudent verses what is legal which usually turns into an opinionated volley in the thread - I will let you decide how you wish to proceed.

BTW: I have seen the same rims optioned on trucks with a 7250 lb RAWR, so I would not exceed that rating even with better tires unless you can find a definitive rating on your actual rims. I used to run those with Michelin tires.

A good estimate would be 250 pounds for the hitch. And at least 20 percent of gross on the pin for the coach. Amazing how fast a one ton single rear wheel truck can use up most if not all the payload. Kind of makes a joke out of the half ton towable fifth wheels. Maybe the fifth wheel only, but certainly not with all the rest of the stuff in the truck. And don't forget diesel is just over seven pounds per gallon, another 200 pounds or more when tank is full. You can probably put a few pounds back into the credit side of the ledger if you remove the stock tailgate and use one that is lighter.



Your cargo capacity is measured with the truck full of all fuels and liquids. So the 3637 is with a full tank of diesel and DEL fuel.

My calculations



You need to ignore the 4220 payload. That is what is in the brochure for an XL truck, no options, with the 6.2 gas. You have a lariat with a diesel. The weight of the diesel and the lariat options are deducted off the 4220, resulting in a net payload for cargo, people and 5th/trailer pin weight of 3637lbs.

Your attached calculator pretty well tells you what you need to look for.

My F350 is around 8,200# loaded so if you used a rough number of 8,000# you're looking at 3,500# cargo. A 3,000# pin at 20% is a loaded 5th wheel of 16,000#.

Yes, I'm a dually but I use a goose neck so I don't have a hitch sitting in the bed. Family of 4 and hitch can easily eat up 1,000# of cargo capacity.

Once you weigh it you have some real numbers to work with.
