That one would be my choice due to it's simplicity
I usually have two Scepter water cans on the back of my Land Cruiser. I run a Super Siphon through the larger of the two small caps on the main cap, and it's just the right size. Prime it and you have nice water flow on hand whenever you want it, no power or such needed. Just tuck the end of the hose into the water can's lid strap when you're not using it.
KISS, I just lay my water can on it's side with a ball valve and short pipe nipple
How can you loose gallons of water by tipping the container on it's side?
