I went this route with my 2 door, 2.0t:



Two years later it still works like a champ. Use it regularly for work, as our vehicles run near a lot of new home construction and pick up nails all the time - actually used it today to plug and fill a flat on one of our fleet vehicles.
Out of the way, but easy to access...

I need to stop buying different offroad vehicles. On the plus side though, it has allowed me to try out a number of different on board and portable air inflation systems. For a vehicle with small tires, that only need low pressure, such as an ATV or UTV, a Viair portable compressor works well. They are a quality compressor that is going to be reliable, and gets the job done with minimal fuss or expense. I own 4 of them that are kept in different off road vehicles. For a vehicle with 37" or bigger tires a Viair is just too slow, and will take three times as long to air up tires compared to an ARB twin.
So for a Jeep the ARB twin is my compressor of choice, hard mounted, so you don't have to worry about not bringing it when you need it. I've tried several different mounting systems. I've used the Grimm underhood mount, an under the passenger seat mount, and the M.O.R.E. mount that mounts it to the driver side of the body tub, right behind the rear seat. Of those three mounting positions I prefer the M.O.R.E. mounting position the best. It keeps the compressor inside where it is protected from weather and engine heat. And it doesn't require modification to the air conditioning ducts under the passenger seat that help keep rear seat passengers cool.
Wanting to maximize its potential lifespan, by having it away from the heat and weather, is what drew me straight to the MORE mount.
It does a great job bringing 40's up from 14 to 32 psi. I've also been nursing a slow leaker on the payloader at work. It takes a little while to bring them up to 70psi, but that's where it's 100% duty cycle really shines.

The ARB still seems a little extreme to me and for what I need. But the Viair portable pump seems to be a reasonable solution...

Obviously, the compressor itself, a very nice bag. The hose is the quick-connect kind, and has an accurate dial gauge (at least mine is dead on when checked with a known gauge). The hose also has a quick deflator that is in-line with the gauge. I actually use it more than my ARB quick deflate that unscrews the valve core.
I added tire patch kit, another pencil type gauge, couple pairs of gloves. It all fits easily in the bag. Just grab it and put it in whatever vehicle I‘m driving. The built-in systems are awesome, but I need a tire kit in multiple vehicles, and I will not spend the money for three ARB twins! Heck I have less than $400 in my entire setup, and it works well, for me at least.
Your bag is all set up! Just a few questions..

1. What size tires are you running? ..I'm running 35s
2. How far down are you deflating to? I like to go down to 17, it's just a number I've stuck with
3. How long does it take to fill each tire to whatever desired PSI you run? ..I like to keep my 35s at 30psi usually

My tires are stock-size KO2's, 33". I run them about 30 psi on road. For the off-roading we do, no rock crawling, mostly forest service roads, I don't NEED to air down often for traction, more for ride comfort. I go to 20 psi.
My Viair is a 300P, their middle of the road unit. I haven't specifically timed airing them back up. Usually we spend that time to get out, stretch our legs, maybe go pee, get a coffee....so it isn't a bother at all. To get the compressor out (it is usually hidden by the camp kitchen, chairs, etc.), connect the battery cables, connect to a tire (I don't have a four-tire setup, never had the need), air all four up to 30 psi, and put everything back up probably takes 12-15 minutes. And that includes the stretching the legs part. I'm perfectly fine with that.

Yes, you could do it quicker with a higher volume compressor and/or a four-tire hookup. But both those would have cost enough to go over my budget, and would maybe save a few minutes at a time, just not worth it as often as I air down. And we would still be doing the other things, and be stopped 15 minutes or so anyway.

Anyone tried using the adventure rack for mounting compressor?
