6 speed transmission questions.
So I came out of the ice age and got a Suburban with the new 6 speed transmission (PRNDM_1). Reading the manual, it seems a little daunting. So how do you use it when towing? And what about steep...

Do you have a 1/2 ton or 3/4 ton? If 3/4 ton, I am thinking you might be able to just drop it into Drive and be good with that size trailer. When approaching a steep downgrade and you think you will need to shift down, just drop it to M. It may automatically drop to the next lower gear than you are in (if cruising in 6th, it might drop to 5th when you go to M). Just shift up and down as needed when needed.
If you have the 1/2 ton with the 3.42, you may have to use M all the time and limit the truck to 5th gear.
The next time you are out with just the truck, drop it into M and shift down a couple of gears to experiment what it does. I don't think you will hurt anything as if you select too low of a gear for the current speed, it should hold the previous gear until it can downshift. Of course, someone behind you might not appreciate you slowing down this way.
Also, if you select 2, it will start in 2nd gear and stay in 2nd gear. Awesome for a 2wd vehicle like mine in deep sand or snow.
