Easy upgrade, Easy to Handle; take a milk crate and add four bottles water to it, which gives you 4 gallon and multiply by the amount of water you want to take with you.
It stores easy also when empty. Also it is easy to use when you fill the FW-tank.
That's how I use them, I have 8 creates and bring along with me as needed.
