Dually payload??

[ruthiebaby88]

How do I figure a dually payload? I drove one and the sticker inside said the cargo rating is 2482#. Do you multiply x2 since it's a dually?

This is a limited truth.
And I'm not sure about that!
It could apply when all four dually rear tires are on a level surface with weight evenly distributed on all four.

It seems there everybody has their own opinions when it comes to cargo capacity. I sacrificed and got a regular cab. The crew cab is what really seems to kill the cargo capacity.
With GM, the cargo capacity took a big jump up in 2011.
My truck glove box sticker say cargo capacity of 5076 lbs.

The axle and wheel bearings will handle at least 10,900 lbs. and the tires should handle at least 11,000 lbs. and with the truck at the rear axle putting down a weight of roughly 3600 lbs. that leaves a payload of 7400 lbs. IF the frame and leaf springs are up to the task.

The leaf springs can be upgraded but not the frame. Ford with its chassis cab version of the F-450 shows an additional 3000 lbs. of payload over the F-450 pickup version and there are notable differences in both the frame and the front suspensions of the two models.

No that trick doesn't work, and why would you do that when the payload (with factory equipment) is posted on the door where he is getting those two numbers???

Hi Tony. The door sticker does not show payload on many older trucks.
Door stickers will show GVWR (and axle ratings) - not payload on older trucks.

The two numbers? They are printed on the tire's sidewall - and indicate maximum tire weight rating.
If you have a dually with OEM tires - take a look.

Heck no it is not!! I wish... Payload when you throw in 150 lbs a person is only 2400lbs. Sticker states 1950 lbs. payload!! Which is a crock of S@$%....Does not stop my truck though handling a 11.3 foot 4000 lbs. Wet Lance TC with no problems with appropriate upgrades.

billyray50 - we were talking about rating a dually, hence the x2. But to test the rear tire theory is your SRW payload 4510#?

Anyone heard of this trick? The Ford salesman told me that they were taught to take the GVWR and subtract the GAWR (rear axle) to obtain a payload rating. Has anyone tried this trick - do you think it's accurate? My impression so far is no, but hard to tell with so many different numbers to look at.

I'm still shocked at the 1 ton DRW with the cargo weight rating of 2450# - even if you add 900# for 6 passengers at 150# each you come up with 3350# which isn't enough for the 10'1" Lance fully loaded. Cars.com estimated payload for this vehicle at 4164# and it's hard to imagine that it wouldn't handle a non-slide Lance camper.

[billyray50]

So with this theory my SRW rear axle is rated at 10,800 lbs. My 19.5 tire the single rating is 4510 lbs. at 110 psi Wheels are rated at 4500 lbs. HMMM....

There are two ratings printed on a dually tire.
One rating states that it is for use on a dually (it's a lower rating).
The other rating states a higher rating (for SRW axle).

Take the lower printed rating on the rear tire - double that number and you will be very, very close to the official payload capacity rating.

I've stated this before in another post.
It is a dumb simple accurate method to find payload capacity (unless the tires are not OEM rated tires).

You need a quick and dirty method of determining payload.
. . .

Interesting idea... My tires are 2560 lbs, so double that is 5120 lbs. My payload is 5362 lbs. So it works in my case. Not sure if it works in every case, but it would be interesting to see how accurate it really is. I think I will stay with real weights, but for an initial guestimate when looking at an unknown truck, it might be a good "rule of thumb".

The rule works on my truck too. . .within a couple hundred pounds.

So dually = tire rating x2

No - it is the lowest rating x2
The rear tires on a dually will/should have two weight ratings - use the lowest weight rating x2.

I just thought it was strange that a DRW 1 ton GMC Sierra would have a max payload of 2482#?

GVWR of 10000, GAVR 4500, GAWR 7500

The tires are 16s.

The truck did seem huge, very long - do you think they used up the weight with an extra long bed?

I would pass on this truck if you can. The weight ratings are too low to justify going to a dually. Depends on the price (and your budget), I'm thinking you might find a newer 3/4 ton that is just as "truck camper capable" as this one.

Ok my tires are 2910 which than would be 5820. The label on the truck reads 5022 so I'm well within. I have a 2008 F350 V10 4X4 with upgrades to shocks etc. I would have to get a lot bigger camper before I start worrying.

If you can get the dealer to cooperate, I would recommend getting the truck weighed. Then you can figure out what the real weights will be when you add the camper of your choice. You may want to check out http://www.visualsc.com/tc_calc.htm. It lets you calculate weights and provides info on the different weight limits.

bighatnohorse - I got excited when I saw a sticker in the glove box that said - For Truck Campers -This is the cargo weight rating- I need to do more research on that number so that I can reconcile it in my head with the tire thing - the tire thing is so much easier I guess I was just worried that the trucks may have had different rating tires placed in the past 10-15 years. The tire trick is producing numbers that sound much more reasonable than the sticker.

So dually = tire rating x2

bjbear -yes I will weigh it eventually, but don't want to spend a lot of time inspecting vehicles just to get to the scale and find out they aren't going to work.

You're looking at used trucks - and you'll need to kiss a lot of pigs before you find that prince.
The rig you want, at your price point, is out there. It will take a lot of looking and patience.
Or a little bit of luck.
