You can see some pics at my Yankee Toys personal page as this is still under construction  

A few photographs of my crude, yet effective On Board Air (OBA). It has 2 plugged ports for future use (1 for the ARB air lockers and 1 for additional connection), and 1 connection to have an air chuck in the front of the truck. The other air chuck is in the back, mounted on a "tee" connector with the drain cock for the tank.

A Mid-80s Cadillac Air-Ride compressor, rated .27 cfm @125 psi. Can fill up a 33"x10.5R15 tire in 10 minutes. With the proper air tank, it might even power some air tools.

Here is a picture of the tank/bumper

Here is a picture of the home made manifold
