I'm planning a solo, long distance, back roads, trip on my DL1K. I do not have an aux fuel tank. I'd like to carry a couple gallons of extra gas -- just in case. I may never need it, but just for peace of mind it would be nice to have available. What is the preferred safe way to carry it? Multiple MSR bottles? A gasoline-specific plastic can? I'll have my Givi side and top bags on during the ride, so securing the cargo will be a point of consideration too.
