i am currently looking for a second compressor that is truck mounted. I currently use two 5.5 hp wheelbarrow type comp. linked together. It works good but I would like something a little better. My main comp is a IR185. I was looking at a 12.5 hp 30 gallon IR rated at 25cfm@175 psi and I figured at least 30cfm at lets say 75 psi. I wanted to know what everyone thought. I dont want to waste my money on something too small but don't want another tow-behind. Opinions?
