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...

While that is true, a high walled RV is more work than any other type of trailer. That's why a TT of 4000 pounds or 10000 pounds uses the same fuel for the same truck.
I tow about 6500 pounds with my 2011 3/4 Ton Burb. I use Tow/Haul mode and M5. I cannot hold 6th gear at 65mph on flat ground, so it takes a little while for the trans to learn (each ignition cycle) not to allow 6th gear.
One difference with using Manual mode (which Hybridhunter perfectly described as a top gear limit) is that you lose most of the engine braking.
Bank of Dad, I hope you enjoy your Suburban as much as we do!
