Towing up grades with "M" and 1 gears

So I have several coaches, but this will be my first attempt pulling a TT up a steeper mountain grade.

I'm towing with a 1 ton Chevy express 3500. I'm a bit "confused" on just how to use this transmission.

P-R-N-D-M-1 are the gears.

So I know what gear 1 is. But the big question is around the M gear.

I've been told to go to M 3 for towing up / down grades. But I'd like a bit more input than just one random stranger. So I came here to have input from several random strangers. :)

I have 2 examples and would like to know what YOU would do if you were driving with my gearset.

1) Driving along, minding your own business, tow button depressed on the dash. Brake controller all good. Suddenly you see one of those yellow signs with a truck going downhill. 7% grade for the next 4 miles. What do you do with speed/gears/etc.?

2) At the bottom of the long hill, you realize you left your wallet at the gas station 10 miles back. Now you turn around and have to drive up 7% for 4 miles. What do you do with speed/gears/etc.?
