The air tank is just a back up for the slow ARB pump and therefore only get used seldom. When next the compressor fails (for the third time) I might consider replacing it with a newer version and then plumbing it to the air tank as well.
The air tank was an experiment and the only cost was for the plumbing bits. As it turns out, a 2.2 gallon tank is not big enough and only pumps one 265/75 from 20 - 35 psi. I need a bigger tank.
Cheers,
