Take a look at the ram 2500 "megacab" with the not so mega payload capacity....not sure this is a productive conversation as the truck should be equipped to the trailers being towed.

 

It's not the towing part that gets folks in trouble, it's the stopping part that seems to cause them problems.

 

OK guys, After 20 years on these forums, two fifth wheels and three super duties I have learned that anyone who starts or contributes to a thread about weight is a glutton for abuse. So here is my response to all the weight mommies.

 

Sennix, do you remember the first round of super duty turbo diesels. I thought you had one. I had a 2001 F250. Fords tow rating for fifth wheels for both 250 and 350 trucks was "20.000 lbs less the weight of the truck". So if applied my short f250 could tow more fifth wheel than a long bed dually.

 

Absolutely correct, And the axle ratings are tire specific. Get better tires carry more. Hard to get enough stuff on a truck to bend an axle housing but over loaded tires have and will blow out.

 

Yes I did. Somehow we managed just fine.

 

Yesterday, I was driving interstate 90 to go to Rochester for a family party. I started approaching a camper that was swaying back and forth once in awhile. It was a decent size, maybe 20 feet or so. Pulling it was a Mercedes SUV that was squatting in the rear and the front end pointing up. Looked like two yuppies with New Hampshire plates. He had the snap on mirror extensions as he truly needed them.

As I got closer, I thought of this thread. I grabbed my phone but dropped it so I couldn't take a picture. There was no way that SUV should have been towing that trailer. Way overloaded. I definitely wanted to be nowhere near them...

 

StanleyZ is correct. Getting higher rated tires will increase the load you can carry.

 

As long as you dont exceed RAWR.

 

I think that was my point. Thr rawr is tire dependent. Increase tire rating and rawr increases. Of course the numbers on the door jamb don’t change. And I guess to cover all the bases yes there is probably an upper limit at which the axle housing or wheel bearings or the axles them selves would fail. But anyone with walking around sense will not load to that level.

 

I see what you are saying. My understanding, which may be wrong, is the RAWR on the sticker is the max rating for the axle itself. Inferior tires, would reduce that number based on max tireload for each tire. Maybe someone can chime in on that.

 

Been waiting for someone with more knowledge to "chime in" also. It does make sense that the rating noted on the door sticker is largely dependent on the tires installed at the factory. Higher rated tires = higher weight ratings, within reason.
I have never seen any documentation on the weight rating solely on an axle.

 

Google search the subject guys...my comments still stand until someone proves otherwise. GAWR on the sticker is max engineering limits set by Ford. Changing to heavier duty wheels/tires does not change that. Changing to lighter duty wheels/tires reduces the load that can be safely carried.

and I stand by my comment:
"In a nut-shell your 10K GVWR 6.7 truck is not rated to carry the weight of most popular fifth wheels."

 

10K on a superduty is no problem. I towed 26K with a windstar for 7 hrs. and then we have the new f-150 that can tow a million miles.
