I wasn't sure where to post this, so Mods, help me out if necessary.

I'm looking for a 12V portable air compressor. It will be used only to air tires. All of my tools are Dewalt Battery driven.
I would like to goto 120PSI. My tires take 80# so that gives me a little buffer.
My TV is a Ford F250, 6.2L with standard battery and stock alternator.
I have a 110V compressor in the 5ver, but if I have a problem on the road, it offers no service. I also store two boat trailers where there is no available power. This compressor will not be used much, but I do want reliability, so the HF stuff just don't interest me. I've decided over the years that I can't afford to buy cheap stuff.
