I am new to all of this, but know it is important to keep my equipment in the upright position. So far, I haven't found a good way to do this in the car while still keeping it conveniently located and useable. During travel I keep my tanks attached, and just leave them in the case and put the case upright in a side pocket of my work bag. At home, I have found toothbrush holders (don't laugh) to be a good method. Any pointers for the newbie?
