Something that I had to consider for my upcoming adventures is availability of fuel. I chose a multi-fuel stove over an alcohol or propane/butane stove as they offer me more flexibility.
In some areas of the world, denatured alcohol and ethanol are not available, at least not legally. And when you are in a foreign country, the last thing you want to do is disrespect the rules and regulations of that country.
The same thing applies to propane and butane. You might find yourself someplace that doesn’t have your brand of butane canister. Plus I’m not crazy about carrying around pressurized fuels in non-refillable canisters that I’ll have to dump into a landfill.
