No go on the new Springs, any ideas?

The compressor is pretty noisy so you wouldn't want it near the cab. It fits perfectly just above the cubby in the fender well, mounted to the bed, and is pretty well protected up there too. If you run the compressor or the control panel anywhere else, the two (or four from the sensors) air lines and wiring need to follow them. This keeps all the air lines (about 19' each which cannot be cut to maintain even volume) in the rear of the truck too. I have only one fused and switched 12g power line to the battery and two air lines running through the frame to the bags. Simple.
