I also have Firestone Ride Rites. I'd HIGHLY recommend an on-board control and compressor. I bought the Dual Air Command II, which has a . 5 gal air tank, and a separate control for each bag. It also comes with a 25' hose which you can attach to a schrader valve mounted where you want to air up whatever you want. I think the compressor is good for 150 psi. Check out my reader's rigs for pics. I got mine from Michigan Truckspring which I think is : truckspring.com.
