Are on board air systems out dated?

I had it on my Jeep. I had a York 210 (maybe 212?) compressor, plumbed with an oiler on the inlet side and an oil/water separator on the output. It went to a manifold that contained an air chuck and the pressure switch and relief valve with another line that lead to a 5 gallon tank mounted in the back and an air chuck on each bumper. You definitely need a high temp braided hose coming off the compressor, rubber ones got to hot and ruptured. For the rest of the system I just use regular 3/8" rubber pushlok hose. It would air up my 36" swampers from 5 to 35 psi in under a minute each. If I cracked the throttle open a little it would be even faster.
