However, in the latest generation 2019+ 2500s, the door stickers are 65psi all the way around, while the 3500s have stayed with the 65/80psi split as before. (at least in the Laramie and higher trims).
The reality all along is that 65psi was enough for tires on the rear axle for a 2500 to meet it's GVWR (which has not changed). For some reason, in the prior generation the manufacturer recommended to "overinflate" the rear tires beyond what was needed for the rated load, but has now adjusted down to more accurately match the rated load.
So, for the OP @Chief Brown, with a 2020 RAM 2500, run the recommended 65psi all the way around when loaded. And, if the ride is harsher than you like when empty, consider airing down a bit on the rear when empty, but air back up when loaded.

The vehicle manufacturer installs OE ties to support the GAWR loads. In doing so they are providing load capacity reserves.
