Payload capacity/tow question

Get rid of aux fuel and get back 450#s instantly

Exactly right. Thats the only thing i haven't bought yet. That will get me to about a thousand off and I'm hoping that maybe when I do get my truck weighed that that 57" 60lb aluminum toolbox with several hundreds lbs of tools sitting at head of bed will take some of that weight and also distribute some to the front axle. I can't really eliminate anything else. I just need to scale it to see where I'm at.

For that heavy of a 5ver, you'll need a class 8 truck.

Used class 8’s are very reasonable price wise. Got me looking at class A DP, again.
In good ole days, we just upgraded our trucks for load and made sure we tagged them for the weight. Again, marketing hype is selling these trucks.

I asked a NC DOT tropper about weight. He said to tag it appropriately for the weight. As a non-commercial driver it would have to be obviously overweight (truck riding on stops) to get pulled for weight. Driving erratic/unsafe will get their attention. I would not hesitate to pull a trailer upto about 4500 pin weight. Not really comparable, but the semis go by axle weights, not "payload". I think the payloads are a method to inform folks not familiar with towing.

Payload...it is the amount the truck can have loaded to the base weight until GVWR is reached.

GAWR...the combination of the 2 always exceed GVWR

GVWR is less than combined GAWR...because weight shifts as you pull out or come to a stop.

Payload is GVWR minus base weight.

The semi trucks have a payload to.

It would be registered weight minus base weight.

I work with trains...they have a payload too.
They also have GAWR and GVWR...and combined GAWR is higher than GVWR

Payload on the door jamb is the most it will be. Once you add an accessory...the truck now has less available payload

It looks like the too big of a trailer dilemma is not limited to the 1500 crowd.

Glad we are headed back to tent camping lol

Bein a sd resident , we dont have have to worry about special licences or upgrading our tag weight. I might be way out of line here but I'm not going to worry about the lack luster pl capacity. The books say i can haul a 34k trailer so I'll be fine with a 26k fiver. Most importantly, gcwr won't be exceeded and brakes and motor and tranny are capable of the load. I'll have to go to a scale and check my front and rear axle weights . If I'm not mistaken isn't the rear axle rated for 10k in the advertising. Sounds like my only issue will be on how does the air suspension handle handle the heavy load and at what pint does it trigger an overload. Ill have to research the bags to see what there rated for.

 

[Rich]

I think I've only seen 1 post on the air suspension reaching overload an that was on a srw. Does anyone have any knowledge or facts on the thresholds that Need to be reached to theoretically set this off and what happens.

 

[DevilDodge]

I think something that is being missed by alot of customers is this.

I have run the numbers on both my own truck and the SO and HO dually 2020...the results are the same.

The listed max trailer weight is considering the trailer WITH the TW included.

They only allow for 470lbs in the truck...so you max tow axle weight would be 34110 minus 15%

So they are saying max pin weight is 5117...but this is a tradesman.

Be back in a bit with some numbers...lunch time is over.

 

[DevilDodge]

So on a tradesman there is 6327 lbs til GAWR rear is met. And they are saying to stop at 5100 pin weight. I would venture to guess the airbag overload lights up at 5500lbs on a dually. Just taking. A guess

My door tag based on trim shows pl at 5176 but that didn't include several added features like steps, hitch, tonnue, and toolbox. Excuse my ignorance but what do you mean by they only allow 470 lbs in truck? Are these door tags for pl assuming that so much weight for people and fuel are in the vehicle? That would be a good thing for me as I subtracted our weight again.
I found these couple things in the user Manuel on the air ride suspension and overload but it doesn't say anything about thresholds.
does protection mode mean it will air the bags back up to full capacity so it's not lowered anymore, wich would be fine.

On my dooor tag it shows f axle rating at 6,000 and r axle rating at 9750. I thought i read some where that the rear axle is rated for 10,000. Am i just making that up in my head

Yes. That 10k number is wrong

 

[DevilDodge]

Payload is occupants cargo.

There is no 470lb allowance in the payload number.

It is the towing number.

They allow 300lbs for passengers and the hitch.

So what that means is...in order to hit the max tow number your truck can only have 470lbs added to the base weight. I weigh 295 if you get the drift.

The max tow number is unattainable.

So if your payload is 5176 your truck already lost 414 lbs if max tow by not being a tradesman.

And then you have to take away what you have added over 470 lbs.

Good times

 

[DevilDodge]

@Rich

Here are the numbers empty truck. This includes full fluids but no accessories or passengers or cargo.

Fill in the ??? With what you added. Obviously your allowance will be more than 476 pounds...which means...you are going to be even less max tow.

Once you scale the truck you can change the base weights.

And I am willing to bet the trailer you will have will have more than a 15% pin weight...so that will drastically drop the max trailer weight.

Everyone just has to have a bigger camper lol.
Good times
Oh. And I am a firm believer that the extra axle capacity is for inertia. You know...weight going to the rear when pulling out and weight coming to the front when slowing down. But feel free to figure that in if you want...but that will be less weight on the front wheels...and there is no WDH with a 5th wheel that I know of...

My thoughts. I was bored

 

[DevilDodge]

Oh...and your 5th wheel trailering weight is to be under 30k

My sticker says 9750 for GAWR. Front is 6000 GAWF.

I tow the kitchen sink. Lol

Man dd. Thank you for all your help, I really do appreciate it. I don't need max tow of 34k but the fiver we're considering is gvwr of 25,999. I have the mopar 30 k rated hitch. I love the diagram, you put a lot of thought into that, very grateful sir. So on your (my) chart. you have the rear axle weight at about 3589 lbs empty weight. Yes the pl is 5176 but the rear axle weight can be 9750 and if your number of around 3589 is close, that's a difference of 6161 lbs of rear axle carrying capability. Am I understanding that correct or am I just turned over at this point

Yes. But see my note about the capacity being for inertia. I also think the wheels may be the real limiter. There is a guy with 2 cracked wheels on another site...just saying
