ARB also makes onboard air systems for trucks and Jeeps. I have one on my Jeep, and it works great, but it would take up some room on an ATV and you mostly don't use onboard air all that much. I personally run a compressed air tank on both my ATV and my SxS and keep a cheap SLIME compressor in the SxS box just in case we have a bunch of problems with several machines on a longer ride. It honestly is overkill, but as they say, better to have and not need than need and not have....
