Exactly Grit!! I schooled your tire jocky buddy (C Rer), on this very issue. I know tire max load may be reached at near door sticker pressure, but with heavy tongue wt, more air is better, usually tire max pressure, as marked on the sidewall of a 1/2 ton truck.
I challenged him, to borrow a trailer, since he didn't own one, take it for a tow, with 1K+ hitch wt. Now air his tires to max pressure (51 psi, IIRC) take it for a tow, and report back. He did finally admit, that some more air might be better, but I don't think anyone trusted him to tow their trailer.
I am referring to max sidewall pressure on truck rear, and a bit more than door sticker air on the front of a 1/2 ton, when towing a 7K+ GW trailer.

If you are referring to me, then I call BS on this.
1) I towed a racecar for 5 years.
2) I never use max pressure - mostly because I know how that figure is derived and that it has doesn't have the meaning you think it does.
3) A little extra pressure over the vehicle tire placard will make the vehicle feel more responsive. Might it be helpful when towing? Sure! But I am talking 3 to 5 psi, not the max listed on the sidewall.
