Over weight, right?

[Spankman72]

Ok, so I took my truck with 5ver on to the scales. It only weighs 1 axle at a time on the truck and both axles on the trailer at once.

Obtw, I have a 2019 GMC Sierra 3500hd Denali Dually with the Duramax and I'm towing a GD Solitude 373fb.

The front axle on the truck scaled at 5220 lbs.

The rear axle on the truck 8240 lbs.

Both axles at the same time were 13300 lbs.

That gives me a grand total of 26,760 lbs.

Gmc says the max tow is 22,700 lbs.

Max payload capacity is 6,112 lbs.

Ok, so by my calculations, I am overall 4,060 overweight on towing capacity. Also I am 2,128 overweight on payload.

Does this sound right? Am I not understanding how to add all the axle weights up?

If so, will it be pound for pound of taking items out from the trailer axles to the pinbox to reduce the payload weight?

Thank you in advance. I'm just so frustrated that we got so much weight on board. We are full timing now. Thank God we have not been traveling like this. We were hunkered down for the past year do to family stuff.

You need another trip through the scales without the trailer

Your probably fine, you need to weigh the truck separately. Your tow rating is trailer only, your 26,760# - the weight of the truck. Payload is your 8,240# - the truck empty

Edit for more detail:

Is the payload weight from the door sticker, that sounds high for a 2019. Regardless, say your truck weighs 8,000 without the trailer, take the 26,760-8,000 that the trailer weight (max tow).

When you weight the truck separately the difference of the axle weights empty vs loaded will tell you what your carrying as payload which should fall under the payload capacity of the truck

 

[Hoopy Frood]

Well, you don't list your empty truck weight, so no way to tell what you have for payload, but very unlikely you are over with a payload capacity of 6,000 lbs.

You list max tow as 22,700, and you show a trailer weight of around 15,000 lb. or so. So you're no where near your max trailer weight.

You need to do a bit more research on what the numbers mean.

 

[huntr70]

No, you are doing the numbers wrong.

Max tow rating would be the weight of the trailer, not combined weights.

Payload is weight of the stuff you can put in it, not the total of rear axle loaded.

As stated above, go weight the truck empty, and go from there.

Max payload capacity is 6,112 lbs.

I tried to look into this a bit more but for the life of me I can not find out the GVWR of a 2019 GMC dually. I think that 6112 number is the "brochure" max weight. Meaning a very particular model like a standard cab dually base model. There should be a sticker on the drivers door jamb with the numbers for your exact truck.

GM was the last manufacturer to go to 14K GVWR on dually's, I think in 2020. If I'm right you should have a 13,025 GVWR. I would guess you have somewhere in the low to mid 4K range of payload. My 2024 with a 14K GVWR has 5,164 pounds of payload. But I think its also a bit heavier.

You'll probably be very close, maybe a bit over, but within reason, certainly not 2k+ over on the payload once you get the rest of the numbers you need. You'll have plenty of tow capacity

I dunno about GMC, but a 2018 RAM Tradesman Cummins dually has a payload of 5,900 lb.

 

[Tom Traveler]

JKellerJr nailed it. The GVWR for the 2019 GMC dually is 13,025 lbs. The 6,112 lb payload is for a base model dually, crew cab, 2WD, gas engine (from the 2019 GMC catalog).

Ok gentlemen,

First off, thank you very much for your knowledge & insight. So I went back and weighed the back axle without the trailer.

It weighed 4020 lbs. So I take the weight of the rear axle when I had the trailer, minus the axle weight with no trailer and that should be roughly my payload, not accounting for my truck bed box and the 5th wheel hitch.

8240-4020=4,220 lbs. That is my pin weight (rough payload).

Towing weight would be the trailer axles only? Or the trailer axles plus my pin weight? If so, I'm in good shape.

Thanks again for you help guy's!!!

I got the info from the gmc pdf. It won't let me paste the link.

The towing weight is the trailer weight, i.e. the weight on the axles plus the hitch/tongue weight.

That gets you close but payload is simply the GVWR minus weight of the truck. Anything you add subtracts from payload. Passengers, the dog, tools under the rear seat, extra fire wood or an auxiliary fuel tank etc.

Only weighing the rear axle empty won’t be exact, some pin weight may transfer to the front axle.

I would try and weigh the truck empty but ready to tow. Everything you normally carry. That total weight subtracted from 13,025 will tell you what’s left for pin weight.

Edit: Make sure your full of fuel, DEF etc.

I got the info from the gmc pdf. It won't let me paste the link.

Yea, you can throw that away it’s basically irrelevant for this discussion. The tow rating in accurate but as you see that’s never the limiting factor. The door sticker is what matters and only somewhat as it doesn’t account for anything else added like bed covers, running boards, stuff listed above, etc. Trucks, like trailers, tend to gain weight the longer we have them.

Thank you guy's for the education. I think I now have it figured out and I'm under weight. I really appreciate all the help.

Thanks,

Yeah, and I'm thinking that you will be alright because the next step would be getting a Mack Truck, 18 wheeler

Lol

 

[Spartacus]

Yeah, right, I guess that they can get a F450 but the payload on those are sometime lower than the 350 dually.

 

[WhittleBurner]

Yeah, right, I guess that they can get a F450 but the payload on those are sometime lower than the 350 dually.

The F450 has a higher towing capacity than the F350 while the F350 has a higher payload. A big reason is the construction of the F450 with it's larger brakes front axles and other components that are heavier and beefier making the F450 heavier than the F350.

 

[Spartacus]

Agreed, question, do it matter if I go over my payload capacity on my F450 because everything is bigger?
