I was asked about how I mounted my 10# co2 tank and thought I should share my response;
I not only needed to have access to the tank but needed it to be able to operate while I was driving so it could run my lockers (it needed to be mounted upright). This as you know is not necessary if you are only going to need access to it just to fill a tire quickly (set the bead etc.).
Mine are mounted to the body of the truck.
I cut the carpet then drilled three holes in the floor, filed, spray painted and ran bolts through them.
I lay the carpet back over the bottom of the holder to avoid the metal on metal vibrations.
I found that alone it was not secure enough to keep the whole deal from rattling around so I detached it and…
Just above the pocket and below the speaker I found a strip of sheet metal under the plastic molding. I figured out where to drill lining up two holes through it and the molding.
I ran a long (maybe 6”) but not very thick (1/8-1/4”?) through the sheet metal and secured it to the sheet metal with a lock nut. Put the plastic molding back running the protruding bolts through it and added another lock nut.
I then lined up the detached tank bracket to those bolts and drilled holes through it.
I secured the bracket to those bolts with a nut on one side and a lock nut on the other cutting off the excess of the bolts.
I then bolted the bracket to the floor as before.
It was a lot of work but it does not move now and when I did the other side it went pretty smooth.
