Looking for advice on stove options in remote areas of Peru. I'm planning on trekking a month on the Qhapaq Ñan, and the trail stays almost exclusively above 3000m/10,000ft.

I normally go pocket rocket, but in this part of the country I understand threaded isobutane canisters are non-existent. Also at these elevations, canister pressure would go off a cliff.

Considerations:

I don't boil anything. All my "cooking" is heating up filtered water to warm soak. I've gone weeks on only a partial 8oz isobutane before, but that was at lower elevations.

Resupplies will be max 4-5 days apart, with the resupply points being small rural towns. Gasoline and probably high-proof alcohol should be available.

Temperatures will be low, especially overnight.

I've been looking at the whisperlite international, but it's heaving and bulky.…
