It's pretty clear what the maximum vertical load and maximum trailer GVW are by reading the "warning box"...
•Gross weight of trailer must not exceed 20,000 pounds for part number 94720, or 16,000 pounds for
part number 94716.
If your goose ball hitch is P/N 94720, so not exceed 20,000 pound trailer GVW, or if your goose ball hitch is P/N 94716 do not exceed 16,000 pound trailer GVW.
•Goose Ball vertical weight must not exceed 4,000 pounds for part number 94720, or 3,200 pounds for part number 94716
If your goose ball hitch is P/N 94720, do not exceed a pin weight of 4000 pounds. If your goose ball hitch is P/N 94716 do not exceed a pin weight of 3200 pounds.
To use your "airplane experience", if there's a warning in the manual that says: DO NOT ATTEMPT TO TAKE OFF IF THE TEMPERATURE IS ABOVE 110F
and further in the manual it says, "the maximum takeoff weight is 3000 pounds at temperatures above 100F."
There's no reason to attempt to calculate takeoff weight at 120F.
It's the same with the maximum weights (by part number).
The 94720 is rated 20K/4K "MAXIMUM" and the 94716 is rated 16K/3.2K "MAXIMUM"
Like with your tires, if they are rated 2830 @ 80PSI, there's no reason to question whether they'll support only 2200 @ 80PSI (if my trailer weighs less or if I load less cargo) Any "qualifiers" don't change the overall rating capacity on the tires nor on the hitch.
