One of the main concerns for anyone riding a motorcycle in remote areas is running out of fuel in the middle of nowhere. If you ride a BMW R1200GS Adventure like my brother then you pretty much can go anywhere since it's got a range like a cruise ship. My Super Ténéré with a 6.1 gallon tank has a range from 230 to 275 until dry depending on how you ride it. I have done averages from 38mpg to 45mpg depending on the speed. On the trip to Daytona I saw a worst average of 38mpg but we were doing speeds that I can't mention here. On my usual rides I average 43mpg, not bad for a 1200cc engine.
On my trip to Alaska the bike will be loaded and heavy, the fuel average will probably be on the low side but I won't have any gas problems until I reach Coldfoot, Alaska, the last place with fuel until Deadhorse, aka Prudhoe Bay. Google maps says the distance is 241 miles from Coldfoot to Deadhorse. It would be risky for me to attempt to ride that distance, it's never good to run the bike until it's almost dry anyway.
To take care of the problem I bought a RotopaX 1 Gallon fuel container, the extra fuel will make me much more comfortable during this stretch of the trip.
