F150 asa TV for 5th wheel

Yes they all use 10% conventional 15% fifth wheel and very few will actually list a maximum pin weight anymore. You will see that in most cases the 15% of TWR is very close to the payload capacity except the Ford F-150 HDPP trucks. So if the rated 15% pin is 1755 and the max TWR is 11,700 if you calculate as intended a trailer with 20% pin weight @1,755 lbs would be about 8,775lbs TWR. Every manufacturer that is SAE j2807 compliant uses this method and they are still very stout numbers for a class 2a truck. The industry norm in general is that pin weight need only be less than the available payload and the TWR reflects that. Ford decided to against the norm and rate TWR less than available payload to be SAE compliant and the TWR’s shows it. It is the person that is behind the wheel responsibility to understand and know the limitations of the vehicle which would clear Ford of any liability because the numbers are there in black and white.
