I installed an on board air system in the Camo Beast. After toying around with where to mount it and the tank, I finally decided that I had plenty of room inside my tool box. The system consists of twin Viair compressors. I got the Dual 400C pack. It is rated 33% duty cycle and puts out 4.55cfm at 0psi. In the 90psi range it puts out 2.65cfm. I figured this would be ample considering the main purpose is to inflate tires. So I mounted the compressors and the tank to a piece of 3/4" OAK plywood and ran the necessary wires to the tool box. It works like a champ.
The Flex hose can reach all four tires.
It takes about a couple of minutes to take these 37 from 20# to 35#
