Unless you are disappearing in the desert for weeks..... we found that the 32 pack of bottled water at Dollar General for 3 bucks is most convenient. They can store in one place or several places tucked here an there, and are very easy to pour in a coffee pot or your mouth. They can be refilled at almost every campsite spicket or replenished when you pass another grocery store, or Dollar general. But, that's just us..... much better ideas out there for sure
