I'm guessing that's the same ARB that makes locking differentials?
Yes, they even have a new dual compressor unit, that can power some tools. The arb's are above 200 though.
The vlair units come in different versions, get the one that has the best duty cycle rating that you can afford or willing to spend.
Pressure switch is also the correct route, you might consider mounting the tank under the bed and the compressor in the box, to keep it dry and give you drier air.
As for under the hood, York compressors are where it's at. But cost a bit, unless you can find a salvage and good at fabricating.
