JeepSWAG's Dominion OffRoad OBA Kit
FULL DISCLOSURE: I PROTOTYPED THIS KIT FOR JeepSWAG
BLUF: The Dominion OffRoad "Jeep JK CMF OnBoard Air System" from JeepSWAG (JeepSWAG.com) is a competitively priced, well-designed kit that will meet all your requirements—if you need more air then you are likely towing a full sized shop compressor to fill up the Under Dog float for the Macy's Turkey Day Parade.
As some of you have read from my posts, I believe I come across as a balanced jeeper. I try to stick to the facts of an issue and objectively discuss the pros/cons. With this in mind, I wanted to share my experience with JeepSWAG's Dominion OffRoad OBA system.
I recently installed the kit and could not be more pleased. As a prototype, there were a few kinks (install instructions, etc.), but if given the choice to do it all over again, I would absolutely still put this on my Jeep at the advertised price. In fact, several members of my local club (Jeep Nation in San Antonio—many thanks for all the help!) are also interested in buying one for themselves, and a few want a TJ version (hint...hint).
If you are thinking of going with an OBA system for your Jeep, I can't imagine a better set-up—to include a full-on York compressor—than this "one stop shop" kit. It comes complete with everything you need to have a full setup and even includes in-cab capabilities if you so desire.
Here are a few highlights from my install:
Step 1
Take the kit out of the box and inventory all of your parts and pieces.
Step 2
Go to JeepSWAG's Dominion Offroad kit website, http://www.dominionoffroad.com/jeep_...air/index.html, and review the YouTube videos to familiarize yourself with the concept of how the distribution manifold should be set-up. If you follow the videos exactly, the placements of the various plugs and fixtures won't work in your JK.
Step 3
Find a good location (i.e. workbench or other flat surface) where you can spread out the kit to complete the pre-install phase.
This step is very self-explanatory (especially after watching the videos). Here is a picture of how I built my setup.
Step 4
Begin the preparation of your engine bay. I started by repositioning the brake manifold hose from its original "down" position to an "up" position.
Step 5
Install the tank brackets. Note the automatic transmission cooler lines will be moved later in the install.
Step 6
Install the completed compressor kit onto the brake manifold. Note to keep pressure on the brake manifold bolts once you loosen the nuts as I've "heard" you can cause some vacuum issues if the seal is broken. I'm not 100% certain about this, so any brake guys please speak up and I'll adjust the write-up accordingly.
Once installed, the kit should like very similar to this, with the exception of your personal preference for plugs or add-ons to the distribution manifold. Note the location required for the pressure switch (to clear brake line manifold) and a possible location for the ground.
Step 7
Here is another possible location for additional grounds (e.g. in-cab on/off switch).
Step 8
I believe you'll want to use the extension hose for your intake filter as the compressor's rear is very tight (insert joke here) as it doesn't readily provide any access space to change it out. I installed mine in this location.
Step 9
Install all the plugs on the tank and try a pressure test to check for leaks. It's much easier to identify a leak this way and will save you loads of aggravation if you have to try to fix it after it's installed. Also, attach the hose to the tank and leave it loose until after you have it mounted. It's much easier to deal with attaching it to the distribution manifold rather than the tank in the tight space—although like with all air lines, it's still a pain in the ass.
Step 10
Move the transmission cooler lines below the brackets and wrap them with tape or hose. I cut and used 1" hose and then wrapped with tape to keep them on.
Step 11
Hook up all the wiring and it's ready to go. This kit has enough capacity to run air tools on the trail for short bursts. If you need anything more than that, then you could always add another tank. If that doesn't meet your needs, then you need to bring along a shop-sized air compressor.
Although I haven't confirmed this yet, it might get a little tight when trying to replace the spark plugs, but isn't that part of the fun in owning a Jeep?
Again, if had to do this all over, I would absolutely install this kit on my Jeep. Once JeepSWAG updates the YouTube videos and install instructions, it will go from being a great, to the perfect OBA kit.

I have this air compressor setup and man it is great! 
For me, I had to rotate the air tank to ride a bit higher in the engine bay.
I often get asked how much it cost me to get the system installed, FREE!
The videos help a great deal.
Plan out your bench work and where you run your lines.
I don't worry about the airing down, i just do it every time I'm off road. Airing up all my tires (35") before duty cycle is very easy.
