I usually carry a couple of extra 20# tanks when I go hunting. They can easily be exchanged since there is no where close to have tanks filled. I have those plastic tank foot things that make them sit upright and very stable. I carry them in the pass through basement which is directly behind the wall adjacent to my 30# tanks that came with the unit. How would this be any more dangerous than that? They are within an inch of the other tanks only separated by a piece of plywood.
