@RET2 I agree with you on the whole "easier to store bottles" thing. However, I'm trying to reduce the single use plastic bottles where I can. I figured a can that can be refilled would be easier. We would have to put some reusable water bottles in the cool box while we drive. So the process would be, finish our "drinking" bottle, wife takes out water from cool box, fills up drinking bottle, then refills cool box container.
@Artie mentioned the other cans, which have mixed reviews on Amazon. I like the idea of that spigot, but it seems that in practice, it's hit or miss.
I'm probably making this whole process more difficult that it should be. Maybe a jerry can with hand pump?
