GVWR

10,900 gvwr 2018 F350 super duty with camper package
that came with a camper certification certificate that said use no more than 3200 lbs when using a slide camper?
6780 rear axle
4850 front axle
Lance 975 weighs 4300 wet after options were installed although rear door sticker says 3261lbs
My question is when you change your rims and tires to 19.5 what is your rear axle weight rating changed to...cant be 6780 still can it?

Technically the RAWR won't change. However the capability of the truck changes. Your rear suspension may be the weak point, after changing the tires/wheels, and may need upgrading, or bags added.

This is how I come to my conclusion to not exceeding GVWR.

Here is what it says in the owner manual and tow guides.

“Note:
Trailer tongue (trailer king pin for 5th-wheel towing) load weight should be 10% (15% for 5th-wheel towing) of total loaded trailer weight. Make sure vehicle payload (reduce by option weight) will accommodate trailer tongue (trailer king pin for 5th-wheel towing) load weight and weight of passengers and cargo added to towing vehicle. Addition of trailer tongue (trailer king pin for 5th-wheel towing) load weight and weight of passengers and cargo must not cause vehicle weights to exceed rear GAWR or GVWR. These ratings can be found on the vehicle Federal Safety Compliance Certification Label.”

—OR—
Just take the word or a few very active posters that the factory information is incorrect and you can ignore manufactures GVWR but you should honor the manufactures ratings for the Axles (GAWR) which both are listed on the Federal Safety Compliance Certification.

Next I contacted GMC Commercial Sales and ask about exceeding GVWR and loaded to GAWR and they sent me this link and this is the GMC official position.

I believe that it is very slim chance that you going to get ticketed for being over your trucks GVWR of even the GAWR/GCWR/tire ratings. My research turned to the legal side started at the link below.

“Towing in excess of the vehicle manufactures’s weight limits could not only prove dangerous but could be considered negligent In the event of an accident with an overweight personal vehicle, you could be held responsible for higher awards in a lawsuit for damages to other people, vehicles or property.”

Still not total convinced I made an appointment with my trusted family lawyer and he explained how manufactures specs on all kinds of products are used in civil court to gain higher awards and there doesn’t have to be a law prohibiting exceeding manufacture specs to play a role in court. The towing guids and the Trucks User manual will be gospile in civil court. The other question you might want to ask is what happens if a lawsuit exceeds my limits on my insurance policy and how to protect yourself. That question can’t be answered unless someone knows what assets would be exposed and what’s your income level. That was an eye opening meeting.

Also check with the local State Patrol, DOT scales operator, and a CDL Training center they agreed you should never exceed you GVWR and load to GAWR.

This is where my research led me and now I’m going to called the weight police and attacked. Your research may lead you in a different conclusion. Everything in life has risk but you have decided if the rewards are worth the risk. In my case towing above GVWR was not worth the risk.



What seemed strange to me that GVWR, GAWR GCWR, tire ratings are all manufacture ratings why would ignore just one but GAWR is not to be exceeded.

I love it when people say that the little lady behind the counter at the county offices can increase the payload of 1/2 ton truck to over 14,000 pounds that were set by engineers at the manufacturer sets. I guess those little ladies now have engineering degrees to work there. LOL

In the real world...there are people who follow the rules to a tee and then there are those who don't. Go figure. I believe everyone's idea of what rig set up is comfortable for them to drive is their own personal comfort level. I drove semi for over 30 years maybe my comfort level for driving big rigs are at a higher level. Companies had us over the road with all types of loads (tons) and incapacities. The laws allow them to operate in this manner until something happens. Most of the accidents with semi's were operator error, to tired. I have a CDL and will make sure the registration is correct because if stopped and weighed I will have been held to a higher standard due to having a CDL. I wont be able to say, "I didn't know" From what I am seeing on the forums almost everyone is above the ratings put on Fords F350, they ignore it, wont talk about it, or tell me they dont know what their rig weighs. I ordered a basic F350 with less than $1000 of optional equipment. 3.73 locking axle 110/400 watt outlet, remote start and a camper package. I am concerned with weight, reasoning for going from 18 to 19.5 tires and rims. The total weight of my camper and truck is 12,200 including 660lbs of tonque. My tires Michelin XRV total capacity are 16320lbs for 4 tires. The only reason for a dually would be stability in winds to keep some butt checks from tightening up however semi drivers know when its windy they slow down or pull off the road. Lances are know for being heavy. Mine says 3261 before manufacturer options. Actually weighed 4300 dry. My wife is a paralegal. She knows legaleeze and the legal system well. Some people do what they are comfortable doing and some do what they are told.
Happy Camping!

Any helpful suggestions will be appreciated.
Thanks!

OP has a Lance 855 truck camper...some how his weight question got posted in the tow vehicle forum. Maybe the mod/adm can move him over there where some most likely have the same truck/truck camper combo.

Great combo match up. All steer and drive axles under ratings. If his F250 has the heavy service pack or camper package it has the same suspension as the F350srw...and of course most know the rest of the truck is the same as.

There's where you make an assumption. How do you know engineers decided those numbers, particularly when you consider how many rating numbers are conveniently just under tax or other legal categories? You can also purchase different GVWR stickers on identical hardware.

Also consider that GAWR is listed with specific OEM tire sizes. What do the ratings mean when those are changed? No applicable? The same?

Not even "ratings" are clear cut.

The statement below that's in the manual that was supplied with your truck and the towing guides aren't clear-cut.

Ford markets F350 srw trucks with 13 different gvwr ranging from 10000 lb up to 11500 lbs.
This gets posted all the time on rv websites but a few rv folks don't seem to comprehend the truck maker may use different GVWR for the same exact truck when we look at Fords specs.
One example is a F350 srw in a 11500 gvwr or the same exact truck with a 10000 gvwr. And several other models with different GVWRs.

Ford F150 has 19 different GVWRs from 6000 on up to 8200 lbs ....but only around 5 different chassis/power trains.
GVWR or GVWR based payloads aren't the holy grail for how much load a truck can legally/safely carry.
