howson I think you hit that nail on the head! This truck is a unicorn and that might explain why its hard to determine that actual towing capacity. I have searched thousands of Rams, Chevys and Fords and have landed on this one as its a totally loaded Lariat with 360 camera (a must for me) and a lot of other safety and convenience features for not too much $$$(by today's standards). The only thing that gives me pause is that its a extended cab and I have a 6 year in a car seat. Thanks for everything. -
Rob hit the nail right on the head. The entry at the bottom of the chart must be for a DRW truck, thats why the GCWR is so much higher. I am used to seeing the chart in post 2 which shows for a F350 SRW Super Cab 4x4 its 15,900 regardless of gearing. That makes a lot more sense. Still well above your trailer weight.Originally posted by Cate&Rob View Post
It goes without saying since you obviously are doing your research, that with a fifth wheel in particular payload is almost always going to be your limiting factor. The reverse of that tends to be true, if you are within payload you are almost always (if not always) going to be within GCWR. I would have been surprised to see you had enough payload but were short on tow capacity or GCWR.

dgerfan -- I can't add anything to your actual question, but permit me to comment that whoever purchased that truck originally must have special-ordered it. A 3.31 gear ratio is uncommon to find on a dealer's lot. In fact every single truck I looked at (on a dealer's lot) came with the 3.55 gear set. Between the ridiculous torque of the 6.7 motor and the 3.31 gearing it certainly won't lack for ability to launch, evenly heavily loaded. The penalty, of course, is highway mileage with that gear ratio. Not a terrible amount, but over time 1 to 2 mpg adds up.

I have also been shopping trucks and completely agree . . . all the info is posted on a door label for a GM and a complicated search for a Ford.
I think the info pulled from the chart with post #2 is for a DRW and you are asking about a SRW. The 5th wheel number that I see for that column is 15,700.
FWIW . . . the more extensive research that I have done on a 2021 F350 CC SRW is in the 15K ballpark (definitely not 23K), although payload is now significantly less than 3500 lbs.

dgerfan Well I have to admit you have me kind of stumped. I consider myself pretty good with the Ford numbers but have never come across this before. From everything you said I think you probably have the 28,700 GCWR, but for kicks I went out and checked my stickers and sure enough it is not printed anywhere. You are correct though, reading those footnotes and given you have the 11,500 package the only option that fits is the 28,700 number.
The good news is it probably does not matter until you upgrade again. The only two possibilities for that wheelbase with the diesel motor and your 18" tires are both greater than your 12k trailer, so you should be fine. You are either fine by a wide margin (2,700 pounds) or a huge margin (8,800 pounds).Leave a comment:

I found this on a Sherwood Ford website. If this is correct it is 23,500.

Determining GCWR for Ford F-350
All I need your help! We made a mistake a couple years ago and purchased a gas truck to tow our 8k travel trailer. The truck was more than capable for the no slide travel trailer but we quickly moved to a 36ft 5th wheel that weighs close to 12k. And once we headed West we had difficulty stopping when going down steep grades and struggled in 1st or 2nd gear to make it up these grades. Truck brakes heated up and caused the truck to convulse even after adding disc brakes to the 5ver and putting the gain up to 9. Its time for a diesel truck! Please note we always managed to stay within our Truck and Trailer GVWR, Towing capacity, etc.
I'm looking at a 2017 Ford F-350 which is at a Chevy dealer and the salesperson can't insure what the towing capacity is. He called a Ford store and asked a salesperson to lookup by VIN the towing capacity of the truck. Per the salesperson it can tow 17,000lbs. Well 17,000lbs towing capacity isn't event listed on the 2017 Ford RV & Trailer Towing Guide and I'm not aware of anyway to lookup a Ford Truck's towing capacity by VIN. Here are the specs for the truck in question:
2017 F350 SRW 4x4 Supercab 148" WB
11,500 GVWR
3.31 Axle Ratio
Payload: 3557 lbs (Salesperson send me a picture of the Tire and Loading Information sticker)
Front GAWR: 5200lbs
Rear GAWR: 7230lbs
Tires: LT275/70R18E 125/122R
On the 2017 Ford RV & Trailer Towing Guide when I look in the F-350 SRW Super Duty Pickups 5th-Wheel/Gooseneck Towing section then go to the 3.31 Axle Ratio section and then going to the 4x4 148" WB 6-3/4' Box column. There is only two GCWRs that have a towing number however I don't know the GCWR for this truck and most of them have a annotation (3) = Optional 10,000-lb GVWR Package (68D) however this truck has a 11,500 GVWR.
Why can't Ford be as easy as Chevy/GMC and RAM are. GM puts the sticker on the door and RAM has a lookup by VIN.
Any help is much appreciated. Also I realize that whatever is discussed here isn't gospel and I and I only are responsible for making sure that I'm within compliance.
