What's going on everyone, just wanted to share my new on board air compressor setup for my truck. I was debating on getting an ARB dual air compressor but couldn't justify the price, so I was looking at the Smitty Built 2781 and the All Top ATACR180L. I ended up going with the All Top compressor, as it had a higher CFM rating.
As for the mounting, I was debating on putting it under the hood but was concerned about excess heat and running my air line all the way to the rear of the truck, where I wanted my outlet located. So I put the compressor where the jack was located behind the rear seat. I was gonna build an aluminum plate to mount it, but ended up using some 3/4" plywood with some heat reflecting tape. I removed the insulation behind the seat against the back wall of the truck to make a little extra room and keep the heat from the compressor combusting the fabric.
Now for the wiring of this thing. I have the compressor wired into my second battery mounted just below the rear of the cab. So I used the original grommet that was in the back of the truck and fished the wire down below. I installed a switch on the side panel behind the seat so it's easily accessible with the seat up or down. But in most cases the seat will be down anyways.
I ran my air line through the back wall of the truck by drilling a 7/8" hole, then fishing the air line down below. I zip tied the hose along the frame then along the bed cross membes, finally leading to my tank (4gal) where the spare tire went. I no longer need a spare tire as I had done a level with 35's almost two years ago now. Anyways, from the tanks I have an air line going to a connection port just under the rear bumper, where I can connect my 50' hose and do whatever I need, fill up tires, use a blow gun, or even run air tools (but probably not for too long).
Modification of the All Top air compressor:
So before buying the all top, I was set on buying the Smitty Built. So Googling around I found the "2781 mod". This modification is just installing a pressure switch into the pump and snipping some wires to allow the compressor to turn on or off when the pressure drops to 70psi or reaches 110psi. The compressor is rated to 150psi and just had a relief valve to purge excess pressure once it got to 150psi. So the thing would still be running when it was at max PSI, it's just going "pop pop pop" every second purging air. Totally annoying and definitely not safe for what I had planned to use it for. So all these modifications available for the Smitty Built compressor is doable on the All Top. So I spent about an hour soldering all new pipes and making everything fit in such a small spot. Did a bench top test first to make sure it would turn on and off at the desired pressure, and also make sure I had no leaks. All was good. So into the truck it went.
Anyways that's my write up on my installation. Nothing new as I know it's been done before on previous generation trucks and I'm sure on this generation, but just haven't seen anything showcasing all of this.
