Here is my question. Me and a buddy are splitting the weight on several items and we were wondering if we both need our jet boils? We are carrying Mountain House meals and were wondering if we can just use one for both of us?? If so is two small cans of fuel enough for 8 nights in the backcountry or should we have 3 or 4 cans? We will also boil water in the morning for coffee. But mainly four water boils a day.
