KC10Chief....Ford, as does Toyota, GM and RAM (I'm not sure about Nissan) all follow the SAE J2807 towing specification, so your payload numbers are not as bad as you think. Those numbers already include 300 lbs for the driver and passenger along with 70 lbs for extra hitch equipment.
I tried to find an free actual copy of the spec, but failed. I did find the following info from this web page. https://jalopnik.com/what-is-sae-j2807-what-does-it-mean-for-trucks-1593305929
"New calculations for trailer weight ratings: In addition to the performance standards, SAE J2807 also uses a specific set of assumptions to calculate maximum trailer weight ratings:
For light-duty full-size pickups (GVWR < 8,500 lbs.), SAE J2807 assumes that the tow vehicle includes any options with higher than 33 percent penetration; It assumes there is both a driver and passenger in the vehicle, each weighing 150 pounds; It assumes that tow vehicles also include up to 70 pounds of aftermarket hitch equipment (where applicable);"
What does TWR have to do with payload? Absolutely nothing.
