Same truck , when coming down a hill I turn off the tow haul as I do not like it shifting for me , tends to really get the revs above what I like . I will shift manually , maybe it is just me .

OEM's spend many millions of dollars calibrating the computer to properly select gears. I trust they know how to put the trans in the correct gears.

The only thing the computer does to "select gears" when going down hill with tow haul on is continue to downshift anytime it can to try to keep slowing the truck down. Personally, I am not a fan of it either. My first choice would be to have paddles where you could actually determine which gear you go in. Shifting manually really isn't an option as the only thing the toggle does is limits the top available gear.

Long way of saying that there is room for improvement here, and the computer most certainly does not know best.

I am not familiar with the Ram transmissions, but my Ford has M (manual) available to select. In this mode, it does shift manually, needing to be shifted up/down with the paddles.

I don't use T/H on a long steep decent, as it will lower the gear, each time braking, and end up with too low of speed, and higher rpm than I want. Using the manual mode in my Ford, is IMO, a much better choice for long downhills of 7% or more.
