I have been looking through the 2019 Ford Trailer Towing Selector (Towing Selector Link) and the numbers for the SuperCrew 157" wheelbase (6.5' bed) 5th wheel towing capacities leave me scratching my head. For the 145" wheelbase (5.5' bed), there is a few hundred pounds difference in the 2wd vs 4wd max ratings for a truck with Max Trailer Tow and 20" wheels (2wd = 10,300 and 4wd = 10,000). That seems reasonable since the extra components for 4wd do weigh more. Looking through the other entries in the table, that small delta seems to be consistent between 2wd and 4wd, EXCEPT for the max GCWRs with the 6.5' bed. Specifically, for the maximum SuperCrew 157" wheelbase trucks, in the line for GCWR = 18,400 pounds, the maxes differ by a whopping 1,400 pounds (2wd = 11,800 and 4wd = 10,400).

I searched on the forum and on Google, but my search fu was once again insufficient to the task. Does anyone know why the extra foot of wheelbase inflicts such a huge penalty in 4wd GCWR compared to the 2wd???

It is a payload issue. The non-hdpp F150 is payload limited before GCWR limited for 5ths.. For some reason the 157” 2x4 has a 7000 lb gvwr while the 4x4 is 7050. In most other configurations the 2x4 is 250 lbs less gvwr offsetting the weight of the 4x4, and resulting in the same payload capacity.

If you look, the 163” supercab has the same gap.

The 2x4 gets an extra 210 lbs of payload. That works out to an extra 1400 lbs of 5th wheel weight when using a 15% pin.

Off topic, so i apologize, but looking at that chart, Im seeing my truck has a maximum tow weight of 9100 lbs. 2019 Super Crew 5.0L 3.55. 145" wheelbase 4x4. For some reason I had thought my rating was lower than that. I realize the limiting factor is usually payload though. Per my door sticker mine is 1989 lbs payload. My GVW is 7000 lbs, but I don’t see the combined truck/trailer weight.

Im surprised though at the difference between gear sets. For my truck.....a 3.31 is lowered by only 100 lbs., but a 3.73 gets an increase of 1800 lbs. What am I missing, or how is that possible? And what are the specs on my truck really?

I am interested in the answer to your question as well.

Thanks mass-hole, that makes sense from the math perspective. I did not realize some of the trucks had a larger payload difference, all the ones I have looked at on the lots have had 7000 or 7050 GVWR ratings on their yellow stickers, which I thought would translate to only 333 pounds difference with a 15% pin weight.

The towing selector guide makes for some interesting reading....

And don't forget to read and understand the fine print and footnotes.

The lowest limit/rate on any single component is your limit.

As has been pointed out 1320 MINUS the weight of your WDH is the limit on a Tag trailer. Because the receiver is rated for 1320. REGARDLESS of Payload or tow rating.

If you have a low payload, that becomes a max limit as well.

The most restrictive limt/rating is the limit for your individual truck.

Yes my truck's payload is shown as a whopping 1,699 on the door jamb sticker (2019 Lariat Screw 6.5' bed, 502A, 4wd, max tow, no moonroof). Only 350 pounds more than my old Honda Ridgeline daily driver , but it will meet my needs for daily driver usage with a lot more bling and toys. I still have my 1-ton dually for heavy work.

Won't be able to do much legal goosenecking though, with me in the drivers seat and the usual lug-along stuff that will limit to around 9000 pounds of tow, more likely 8000.
