Perhaps Red Chili will chime in. IRRC, he has the Extreme Air, or something very similar, on his mini. I think he may have two, but I could be wrong.
Something else I've seen done Matt, if you have room for it, is the 4 tire hook ups, such as the one 4crawler has, which makes the air compressor slowness almost a cool thing, as you can sit and BS for a while without having to check and move the compressor constantly. Essentially, hook it up, and walk away. Time it once at home, and just watch your watch (clever
) while talking with buddies, then go shut it down at the appropriate time. Also has the added benefit of getting all 4 tires to the exact same pressure every time.
