I use a little different strategy with a lue barrel.  I have two a 10 gallon and a 12 gallon.  Both were able to be placed inside an army duffle bag with backpacking straps to make it easier to carry.  I hide them away from camp, not close to a trailm under brush.  The olive green bag makes hiding easier.  I just make sure no one has touched it after handling food, to keep odors off of the fabric.  I am doing first solo this summer and the barrels are two big for just one person, but I will figure some thing out.  I would like to be able to keep everything for me in one pack, food, clothes, tent, sleeping pad, cook gear, tarp... you know everything  ;D
