Air tank to go with OBA?

[cbbr]

I am going to install an ARB twin in my 2000 LC100. I think that an air tank would be handy. My sliders are Any of you guys mount a tank underneath?

I have both sliders plumbed as air tanks, probably around 2 gallons total volume. It helps give a good blast of air for reseating tire beads or running air tools if you wanted to. Also saves air up time somewhat as you can pressurize the system prior to stopping to air up. Probably not much of a time saver but a little anyway.
