Can’t wait to see how you work out the onboard air compressor. Would be really interested in trying this!
I have one on every truck I own.......... on the Tacoma I mounted it below the Dvr's headlight behind the bumper. Totally hidden, the air tank is mounted behind the Pass headlight. I have quick connects at the rear tailgate and near the battery, extremely useful. I used all AN fittings and SS braided fuel line as the supply lines. Expensive route but it'll last forever with no leaks. I have used the cheaper plastic hoses with "push-on" connectors, but they always seem to leak over time.
I also prefer the volume button here. I wonder how difficult relocation would be.
I dont know if you still need this but maybe this.
