What I mean is - if you don't need the extra range, a $15 can will cover the "you should have the ability to transport fuel just in case" requirement.One who is hitting the trails will have something better than a $15 fuel container. Chances are they will spend a bit more on something that is actually going to hold up to abuse and probably have it filled before a trip starts so they can guarantee a longer trip without having to get more fuel.
I don't mess with transporting filled cans unless there is a real risk of running out and have only needed to do so a few times (driving through the Nevada desert, and a few cases where I knew ahead of time that we'd likely hit highway closures and/or gas stations out of service)
