Help understanding the towing guide
https://www.ford.com/resources/ford/...DtyPU_Sep9.pdf
F-350 SRW SUPER DUTY PICKUPS 5th-WHEEL/GOOSENECK TOWING (section) there are three different 5th wheel tow capacities.
11,300 (9990 GVWR?)
12,000 (10000 GVWR?)
20,000 (limited to 18k with 5th wheel) (11,500 GVWR?)
If I order a this set up, 6.7L 4x4 176" WB 8' Box, how do I know what the tow capacity is? YUGE difference of 8k and no explanation of what is required to get the 20k and 11,300 seems really light. My 06 Ram 2500 4x4 is rated at 12k with 600 ft lbs tq and crapy 4 speed auto.
I've seen the explanations on subtracting weight to get your GVWR, but what causes this 8k jump?
Is it the 9900, 10,000, and 11,500 GVWR when your order the truck being the 11,300, 12,000, 20,000 tow capacities?
Not looking for exact numbers, my RV is 13,500 GVWR so it looks like I need the 20k option as the 12k option is way to low. What is required for a SRW to get the 20k tow option?
All pick up trucks in California are considered commercial vehicles and we all pay extra vehicle registration as commercial vehicles so not concerned about higher registration fees, CA already taps us even if it's a daily driver.
Thanks all, will be ordering a 2018 in the next month or two.

Some of the numbers are simply a paper designation used to control registration costs. Mine is 11,500 but you can get it at 11,400 also. Nothing physically changes on the truck itself.
I believe that the lower gear ratio (3.55 for the diesel) may give you a better tow capacity than the 3.31 gears. I opted for 3.55 with my 6.7L.

The Truck GVWR is just the rating for the truck. The GCVWR would be the combination of both truck and trailer.
Bumper pull is not as high as 5th wheel/gooseneck.
The other factor is gearing and cab configurations.
So to zero in on your actuals we have to know the exact truck, the motor, the gearing and 4x4 or 4x2 and the cab configuration.

With 2017 6.7 SRW F350, you'll almost certainly run out of payload before running out of "towing" capacity. The long bed King Ranch I wanted had a 3200# payload. With 1000# for a family of 5, dog, and hitch, that leaves only 2200# for pin, gear, etc. That's likely in the 12k# fifth wheel range, WAY below its tow rating. That's why I ended up with a F450, which is a great truck.

Actually, the SRW 5th wheel rating is the same as the GN rating. It's de-rated because Ford markets their 18k (Reese Elite) 5th wheel hitch with the SRW. Run a higher rated 5th wheel hitch and your rating is the same as the GN. 20,600#.

I too was concerned about the gvw. I stickered at about 3500 carrying capacity, and have a 14,500 lb. fifth wheel with a pin weight at about 2900 lbs.
Given the robust axle and tire ratings, along with the fifth wheel towing ratings, it seemed to me that the gvw was artificially low....but I figured I was at my gvw max with two of us and some stuff in the cab so just packed smartly.
Well, 7000+ miles through the Rockies and this combo doesn't even make the rear springs hit the helper springs. My timbren springs don't touch the stops while loaded and stationary.
I think you absolutely must ensure that you stay within your ratings for axle and tires...but that the gvw is a bit of a contrived number for registration and taxation/classification purposes. While I try to stay at or under the GVW, I no longer think it is the most critical number
Others will disagree.

I find it hard to believe that Ford would reduce a tow rating just to sell a hitch when the TWR marketing value is so high. The only logical reason I see the 5th wheel and gooseneck ratings might be different is frontal area.

That would make complete sense and I run a 25k hitch myself in my SRW while towing my 20k+ 5ver. Not sure why Ford doesn't do it that way. Perhaps they feel that marking a hitch with a rating higher than the truck it's used in will lead to confusion and liability.

In some states, yes. In MA where I live, the 26k license class change does not apply to RV's. All RV's of any weight are OK in MA with a standard class D license. If I was to tow an equipment trailer as heavy as my RV, yes, I'd need to go up a class on my DL...
