Airing up after sandy roads: a decent inflator from Costco

zman, right on. The ViaAir would my choice if i did not have CO2. I'll be interested to see how the Costco air compressor does after some hard use. Unless you are really hard core, that may be years down the road to really push the duty cycle. My guess is all the cheaper 12v high volume air compressors are made in China. For all of these, heat is the enemy and they tend to wave the white flag way too easily.
