A "GOOD" 12 Volt Air Compresso r July 09, 2003, 12:10:20 pm Yahoo Message Number: 24326The posted article on 12v compressors reminded me of what some people in Jeep club I belonged to did. They would convert old a/c compressor to on board air compressor. The compressor of choice tended to come from older Cadillac's. Here is a link on how-to if you are so inclined to try doing this. http://www.ifsja.org/tech/misc/cheapair.shtmlThe article doesn't go in to adding another compressor, but using the one that is installed already. If you have the know how to do this part, you can figure out how to add a second compressor. Although, our van chassis don't allow much room for this sort of thing. Anyway, I thought some people here might find this fascinating.-Victor
