With a 5.1 gallon fuel tank, cruising at highway speeds, you should not have to worry about fuel. You should get close to 250 miles a tank or more, the bare minimum would be 200 plus. Just plan your stops. Now if you're riding up the Dalton Highway up in Alaska, different story.
Personally, I do not bother with a camelback, as I tend to rehydrate when I stop to refuel and just buy my drink there. I might carry bottled water with me in my tail bag.
You may also want to consider purchasing a Spot tracker. A GPS tracking device which people can follow your movement in real time, and you can send messages to anyone once you reach your destination safely each night. Keyword "Spot" if you want to do more research. Sold at your local Cycle Gear or mountain climbing retailers.
