This is the same footnote on the HD trucks also so I tend not to worry about payload as long as I do not exceeded the axle weights and truck and total combined weights of trailer and truck together. Tire loads are part of the GAWRs.
Guess the Ram engineers aren't that smart. "Definition of 'Mutually Exclusive'. A statistical term used to describe a situation where the occurrence of one event is not influenced or caused by another event." Real world maximum trailer weight is what is left over after subtracting loaded, wet truck weight from the GCWR. So, the more an owner uses up payload the less is left over for the trailer weight and the two are linked and therefore, NOT
However, I agree with your position, don't exceed tire/axle ratings is most critical.
