Any of you guys using an on-board 12 volt compressor for airing up? Any other good options out there other than ARB? I know ARB makes a good compressor but I really don't want to drop $500 for something I will only use ever once in a while to air my tires back up after trail riding. I have factory diff lockers so I won't be using them to run air lockers. The other concern is not taking 10 minutes a tire or longer to go from 12 lbs back to street pressure which is 30 - 35 lbs on my 35" tires.
