Being a cheap SOB, and wanting to be able to fill big tires in a reasonable time, I built my own compressor Junkyard Wars style, using a modified Japanese starter motor belt driving a Sankyo refrigeration compressor. This compressor has given pretty reliable service for several years now. As would be expected, it draws some hellacious current (over 100 Amps), but puts out a lot of air at the same time. I don't like to go out to the boondocks without it, and have saved my own bacon as well as several other travelers with it.
I have also set up my dad's GMC motorhome with a direct engine driven Sankyo that is rigged to a pressure switch and automatically keeps his onboard air system at 130 psi. The factory system used motor driven compressors and would take forever to reach full pressure. This system pumps up almost immediately now. For that installation, I have tapped engine oil pressure which is sprayed into the wobble case and returned to the engine crank case. We have even used it to run an impact wrench.
You can pick up one of these compressors at a wrecking yard (and the starter motor too) pretty cheap.
Be Prepared...........the tire deamons stalk those who aren't.
