Looking to purchase a air compressor and wondering what is the smallest size I can get away with while still being able to fill up the tires to 70psi and use air tools?
Highly suggest you look at the Puma 12v compressor. They are extremely popular with the 4x4 community. I stumbled across it just before pulling the trigger on a Viair.
Costs about $200 and blows away anything else in that price range, including Viairs that costs much more, plus it comes with an air tank.
I bought mine from Buzzard Gultch on Ebay. They are one of the few retailers for the unit.
