That just sucks having to go all this trouble. High tech is great until it breaks.
Simpler stuff, like the old times, were more reliable in the long run.
Good luck.
Another idea for fire extinguisher mount.
Thought of this, and going to do it, but thinking of horizontal mount and up high in the back of my Tuffy Box. The jack doesnt leak on its side. Better then moving around loose in the back.
