I hooked up my onboard air. My setup for now is pretty simple. I already had a Viair 450p, so I mounted that up front (ton of well ventilated open space above the skid plate). I converted to JIC4 fittings and ran ARB braided stainless lines to two ARB couplers. One is mounted on the right rear bumper step and the other is on a bracket mounted to the front side step bracket by the driver door. I really only plan using this for roadside issues/normal air-ups. Iām not doing heavy off-road air-drops and refills. The 450p can run 100% duty cycle for an hour- so I donāt think Iād need a tank, but could always add on easy enough if needed later. This was more a project than a necessity and it saves space under the rear seat instead of the compressor bag. The ARB coupler covers will be here this weekā¦ kinda interesting, there are unused hose clips on the front frame that fit the air line perfectly.
