Truck mounted air compressor

Here is my set up. I highly advise you mount your compressor internally. The tiny filter will clog in no time mounting it outside of the cab, the air is just to dirty and dusty. Mine lives underneath the back seat cargo area. The system has a schrader valve you mount to the frame so you can hook up the coil hose to fill air into anything from tires to rubber rafts. The on demand air controller to your air bags is the bomb...air adjustments on the fly is fantastic. One other note is that your airbag brackets be planned out very carefully. They are not just bolt on and go. Many measurements have to be done loaded and unloaded or you will bottom them out so be prepared for some cut and re-welding work... Mine have been modified on the lower brackets to allow for the huge amount of travel the Dodge dually has...they may seem stretched out a bit, but trust me...stock ones out of the box are too tall at least when I did mine. Notice the unloaded and loaded pics, that is a lot of travel up and down. Good luck and you won't regret the upgrade. I hope it works out.
