Rotopax is a slick solution. With my KLR in Alaska I packed two MSR bottles plus stove fuel if things were really bad. Most folks up there who do a long run with temporary gas just use an approved plastic fuel container ( One gallon or so) that you can buy at almost any gas station . They just strap on top when not in use. You fill it up just before an 'anticipated" long run without gas and then empty the contents after 60 miles or so to minimize the container risk. I had one 250 mile run without gas in Alaska but did not use the emergency gas. I always carry at least a MSR bottle on tour. I have been over 200 miles several times without a gas station to include Nevada and West Texas.
