For those of you with diesel HD trucks that lower their tire pressures when not towing, what do you set them to? My Ram calls for 60psi front and 80 in the rear. As most know, this gives a pretty h...

They recommend using those charts unless you want to blindly run what the manufacturer says that is a CYA for them.
Do you seriously think vehicle manufactures don’t know about those charts and don’t use them as one of the criteria when selecting a tire and determining what pressures are optimum for that particular vehicle?
Wilber1 is absolutely correct on this one. Using the chart alone for the TV tire pressure is being blind to the big picture here. My old 06 Silverado had a 25 psi differential 55 front 80 rear which stayed that way for ten years on the same tires without a wear issue. They don’t design them to ride like a luxury car. If you must reduce tire pressure always maintain at least 5-8 psi higher in the rear tires, never go lower then the front. Running in sand or loose dirt is quite different then pavement.
