More from Ford F-350 6.7 V* Diesel 4WD SRW Crew Cab, Long Bed

Ford F-350 6.7 V* Diesel 4WD SRW Crew Cab, Long Bed
Thank you for all the helpful responses. These are the weight recommendations I compiled from the responses from 5 different sites:
Can you tell I’m OCD and obsessed with numbers?...
11,000 1 recommendation
11,850 1
12,000 3
13,500 1
14,500 1
15,000 2
I’ve averaged that out to about 13,000 lbs.

SO, along with the response averages and my calculation results (Assuming that we won’t max the truck out to its GVWR)
I think we will go out on a limb and shoot for a 5er with a
dry weight of 9500-11,000 and/or GVWR under 13,500.

Am I on the right track? I’ll go with the majority answer…

Your figuring sounds solid. The only recommendation I would make is to go with dual rear wheels. The ride will be more stable with a 5er and give you some extra GVWR to play with for a safety cushion.

I read some of your other thread. Everybody can't be right.

Your truck will tow a bigger 5th wheel trailer than the 13,000#s you have settled on.

Here is the official Ford chart.

2015 Ford Super Duty | View Towing Specifications | Ford.com

I see your truck rated for 15,700#s - 5th wheel, diesel, crew cab, 4x4, SRW

Looking at your numbers from your other thread...

In other words, are there other considerations and options that would increase our towing capacity?
Here are our numbers:
GCWR 23,500
GVWR 11,500
GAWR-Front 6,000 actual: 5200 weighed on scale
GAWR-Rear 7,000 actual: 3820 weighed on scale
GVW 9,020 Weighed at scale with passengers, fuel, & cargo (but no 5th wheel hitch)
Max Tow Rating 15,900

Here are our calculations for a 14,500 lb loaded 5th Wheel:
GCWR 23,500
- GVWR 11,500
12,000 3,900 lbs less than quoted towing ability (15,900 lbs)

GCWR 23,500
-GVW 9,020 Actual truck weight GVW
14,480 1420 lbs less than quoted towing ability (15,900 lbs)

Pin wt. for 14,500 lb 5ver x 20% = 2900 lbs

2,900 Pin Wt for trailer adds 2900 lbs to back of truck
+ 9,020 Truck Wt
420 lbs OVER truck's GVWR of 11,500 lbs
and just 312 lbs UNDER rear-axle limit of 7000 lbs
2900 + 3788= 6688 pin Wt + rear axle wt

Hitch weight is the big limitation to you truck (price of SRW).

Here is the Ford towing guide: Ford Towing Guides | The Official Site of Ford Vehicles | Ford.com

They say hitch weight/king pin weight) should be 15%-25% of trailer weight.

My hitch weight (Chevy truck and toyhauler) runs around 17.5%

Truck and Trailer -
Steer axle - 4480
Drive axle - 5960
Trailer axle - 10820
Gross Weight - 21260

Truck only -
steer axle - 4500
drive axle - 3660
gross weight - 8160
I can use these numbers to figure my hitch weigh and trailer weight.
hitch weight - 5960 - 3660 = 2300 (17.5%)
trailer weight - 10820 + 2300 = 13120 (trailer rated to 13,800#)

Conclusion - you need to be cautious about hitch weight if you buy a trailer that grosses out more then 13000#.

There is a thread on this forum where people posted the weight of their rigs. I can't find it right now. It was eyeopening for me to see the variation of pin weight percentages between different manufacturers.

I've never heard of anyone buying a trailer for their truck based on what the majority of a dozen or so answers were on a RV forum.
We have some folks on this forum that claim a DRW is needed for anything over 10k-12k lbs or a mythical length.

I would use Fords tow ratings recommendations for your trucks configuration.
