Mount the compressor under the bed where ever you can find the room. As for the controller, that depends on how often you need to adjust it, if you're not using an "Air ride" system and making it "dance" I wouldn't see a need to have in cab control so I'd mount the controller in the bed or down some where close to the hitch.

thanks i still would like more advice the compressor under the bed i like
the gage and controller is nor wheather proof and needs to be inside
