A lot of people suggest mountain bike gearing with a crank of something like 44/32/22 and a 11/32 cassette. That would result in a highest gear that is 5.82 times as big as the lowest gear.

I am running a 52/42/24 front with 11/32 cassette, that gives me a high gear that is 6.30 times higher than the lowest gear.

Some people are sold on Rohloff hubs for touring. (I have never seen one.) They have a high gear that is something like 5.26 times greater than the lowest gear.

If you wanted to tour on a 1 X 10, your highest gear would probably be no more than roughly 3 times as big as your lowest gear. I would not be happy with such gearing. If you had a compact double, that would at least increase your range to roughly 4.2 but if it was me I would want a triple in the mountains.
