For the tire experts?
You replace tires with a load, or 2, range higher so in theory you can lower the max psi which to me increases sidewall flex thereby increasing temperatures, so why not inflate to max psi for either load range? I've always ran max psi regardless of load rating with no noticable difference in ride in the truck with higher or lower psi, no one is riding back for the ride to bother anyway.
As to more jarring on the RV with higher psi doing harm, how would you know if it was tire inflation, our wonderful highways or high quality built RVs, things fall apart while parked.
I will continue to inflate the tires to max psi as I have for the past 40+ years towing trailers, but it might be good info for others with no experience.
