What number do you use to figure max pin weight for a fifth wheel.

10,000# GVWR

Front 5200#

Rear 6340#

2025 Passenger and Cargo

Trailer tow package
Fifth wheel prep
20" tires
2017 KR 6.7L diesel

My figures are pretty light.

Personally, I couldn't get there from that info. We're full timers, and I weight the truck (ready to tow, full tank to include DEF, everyone on board, picnic lunch, etc) at a nearby CAT scale. I then take the lessor of two numbers: 1) GVWR - CAT scale weight of the truck or 2) Max rear axle weight rating minus the rear axle measured at the CAT scale. Costs me $9 to weight the truck. We make a morning outing of it. David

 

Ford will tell you not to exceed any of the three weight ratings (10K., 5200, and 6340). As a technical matter, the 10K GWVR and the 2025 payload specs are your "official" limits.

Based on your previous post, it looks like you could handle a pin weight in the 1200 lb. range.

Now, as a practical matter...

I've always gone by the "passenger and cargo" number as the maximum pin weight, with the caveat that if you hit that number, you'll be over it as soon as the dog jumps in. That number minus your people/stuff/everything you load in then becomes the pin weight not to go over.

On a related note, I've heard different things on what the "passenger plus cargo" number already takes into account - things like "150 lb driver plus half tank of fuel" etc - but I am not sure if those are true.

 

The yellow tire and weight sticker gives you the max GVW and cargo carrying capacity rating for your vehicle and tells you the allowable additional weight you can carry over and above the truck and a tank of fuel....doesn't include driver weight. You can get your actual truck weight by subtracting the cargo capacity from the GVW rating.

The GVW is determined by the manufacturer based upon any number of variables...including keeping warranty costs low, weak link considerations, cooling considerations, braking considerations, ensuring easy registration in a certain state or two with crazy weight and licensing requirements. This is where it gets fuzzy, because the white sticker on your door gives you the axle and tire weight ratings. You will likely find that these ratings, once you start looking, are much higher than the printed cargo capacity for your vehicle. You will also find that the published capacities for your truck are way higher than the posted cargo capacity and more in line with the axle and tire ratings.

For me, those tire and axle ratings are real world maximums and I want to be no more than 80% of them. I am less strict about the cargo capacity and gvw...but like to use it as a goal.

Others will have their own opinions, while some are blissfully ignorant. If you are at or near GVW, you can add Timbren springs, airbags etc. to give you a more stable tow...but they will not change your legal GVW.

 

You would be correct but there are no fifth wheelers out there with a pin weight of 1400-1500#.

Heck, even at 1400Lbs no 2017 KR F250 should ever have a 5th wheel attached. That amazes me.
1880 is the cargo limit.
Me, wife, dogs and a snack are 400.

How are F250 owners pulling 5th wheels?

 

My Open Range 5er has a pin weight of 1435 lbs. I suppose it could be the only one with that pin weight, but I doubt it.
