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?

[bighatnohorse]

Yes, looking at a purchasing a used truck and being told to weigh the truck isn't very practical advice.

When looking at a used dually, look at the rear tire's printed ratings.
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 determing payload.
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.

Tonymull - I have a new theory - today I looked at a 1996 Chevy Silverado 2500. The sticker in the glove box said the cargo weight rating was 1208. Perhaps they are including a 150$ person in every seat? 6 people x 150 = 900# That would at least bring the rating up to 2108 including people. That still sounds low, the tires were rated to 3000#.

I have 2 ideas.
1. The truck companies are over conservative when setting their limits so no one listens to them and everyone is happy. Some people believe it's a marketing ploy to get people to buy larger trucks than they actually need.

2. No one really wants to know what their payload is because it's a huge pain and they just want to get out and have fun, math be damned! If people obeyed their payloads, less campers would be sold and less camping would be done!

I apologize to those who are telling me to weigh the truck, that's great advice, it's just hard to do when you don't own the truck. I don't want to spend a bunch of time inspecting and test driving a truck only to find out the payload is less than what I need - so I've been doing my best to find out before seeing the vehicles.

I worry about payload because I want an easy driving experience with good safe handling.

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?

Is this a 1990 truck with a 454 engine in it? That is no longer a 'very capable' truck. They have improved a LOT over the years.

In 2005, Ford F-350 SRW was rated to carry about 4,000 pounds, and had a GVWR of 11,500 pounds. The Dually F-350 in 2005 was rated around 13,000 GVWR. It did depend on the cab choice, and if you had a diesel engine, then the GVWR went up by about 500 pounds.

You would be better off looking at a newer truck, with a much higher GVWR, or look at a F-450 with a tool box body that is 33" tall, same height as a normal pickup body. The early 'Super Duty" F45 in their VIN number had a 16,000 GVWR and 16" 10 lug rims. So they did not mount the older 2,400 pound rated rims on the heavier truck!

IF you want a lighter curb weight, then the gas engine will be about 400 - 500 pounds less than a diesel model.


Have fun camping!

Yep. Mine weighs



With me (the driver) in it and this much fuel: (enroute to pick up the camper (AF811) from the dealer.)

I'm over the GVWR of my 2009 Silverado Dually right off the camper dealer's lot. This photo was on the way home from the dealer.

Sounds like my old 91 dually. 10k gvw. That was when a 1 ton carried about a ton of weight.

[wintersun]

Usually the dually rear axle is rated for 8,000 lbs. or more as with these trucks the weakest link is the tires and adding 2 more nearly doubles the load capacity. Subtracting the weight of the truck at the drive axles gives an approximate maximum payload.

The problem with the payload ratings is that if you have a crew cab the manufacturer down rates the load to allow 150 lbs. per passenger seat or 750 lbs. with the crew cab configuration.

The rear axle and wheel bearings are rated for at least 8900 lbs. so the weakest link is first the tires and after that the leaf springs followed by the strength of the frame.

There is something else wrong with your numbers. I have a SRW 2500HD that has a payload rating from the factory that is greater than the 2482 pounds mentioned. It is actually less than the payload rating of the new Ford F-150 trucks with 17" wheels.

When I was looking at new trucks on dealers' lots there were always similar trucks with very different payload ratings and the difference was usually with the rims and tires on the two trucks.

Trucks can come with different axles depending upon options and whether the engine is gas or diesel and with different leaf packs and with different rims and tires. All of these factors affect the calculated value that is put on the sticker. Most of these factors are easily corrected by the owner to improve load capacity and handling.

Yes. 😉

[copeland343]

In Louisiana you now have to register your truck based on GCVR not GVWR. So my 2000 F250 is registered for 20,000lbs. That is what Ford stated for all 2000 model F250's and F350's for that year. Every state is different. We now do not have to have single axle trailers or boat trailers inspected new rule.

Are you considering a tc or towing?

The payload capacity of your truck = GVWR - scale weight. It doesn't matter what any sticker, salesman, or brochure says. If you want to know the payload capacity you have to weight the truck.

Now, what sticker are you looking at? Is it the one in the glove box? This one assumes that you have a 150 pound person in every seat in the cab. If this is a 6 passenger crew cab truck then they have subtracted 750 or maybe 900 pounds form the payload for passengers. (I don't remember if they count the driver or not).

If you're look at a '90s Chevy the GVWR is probably around 10,000 and the truck probably weighs about 7,000 empty so you've only got around 3,000 payload. Subtract the passengers and you're down near the number you gave from the "sticker". Yes, it's really sad but that's all that truck is rated to haul.

If you're looking at a 2001 - 2010 Chevy the GVWR should be 11,400. The truck empty probably weights about 7,500. This should leave you around 3,900 pounds of payload. Even subtracting for people should leave over 3,000 pounds for payload.

Did they "use it up with a heavy truck"? Yes. Crew cab, diesel, 4wd, it all adds weight. If you look at a 2011 and newer Chevy the dually should have a GVWR of around 13,000 which helps your payload considerably.

Now you know why the majority of trucks hauling TCs are over their GVWR. Most of us go by axle and tire ratings. My own 2005 Chevy dually is rated for 11,400 but scales at about 13,200 with my family, 11' TC, and boat hitched up. I'm not over the ratings of my tires or axles. I've got many thousands of miles behind me with this set up.

Is it legal? Absolutely, my truck is registered and tagged for 14,000 pounds. I know a lot of people will try to say I'm going to kill someone, I'm going to get sued, etc. That's their opinion. Many many professional "hot shot" truck drivers run dually pick-ups all day everyday over their ratings hauling automobiles, pipe, etc. They are routinely stopped by DOT for inspections and cross the scales at weigh stations. It's perfectly legal.

Trucks can be modified to have a greater payload capacity, not a greater GVWR mind you, but a greater physical capacity. Only licensed up-fitters can change the GVWR. I once saw a truck that started life as a 1500. It had been modified with tandem rear axles, a 500+ cubic inch engine, and a fifth-wheel hitch. It was used to move semi trailers around. I bet the door sticker still said something like 6,400 GVWR. In reality that was capable of much more.

Honest numbers? Yea right. More like 1500 pound in real world payload. GVWR minus real world scaled weight is your honest payload, not some mystical numbers you read somewhere.

I thought that the dual rear wheels changed the calculation since you have more wheels supporting the weight?

why would the door sticker list the weight for singles on a dually truck?

It doesn't.

THe sticker is the rating for that truck. If the truck is an SRW, then the payload rating pertains to the fact that the truck is an SRW.
If it's a DRW, then the sticker lists a weight for it being a DRW.

There is no way to increase the manufacturer's payload rating of a vehicle.

People will "tinker" and add stuff to increase their safety margin, or improve ride and handling, but it does noting the increase the payload rating set forth by the manufacturer.
