Why put an air gauge inside?
Warning: Probable dumb NooB question ahead...
I'm looking at installing a sPod to simplify wiring and they offer a console with an air gauge. Assuming that I will eventually add onboard air, I'm wondering what the benefit would be, if any, to have the gauge inside the vehicle when I'll be using the air outside (fill tires, power tools, etc...)? Is this because it takes so long to fill a tire that you can hangout inside while you wait? What am I missing?
