As for the compressor, afaik a York Compressor is suitable as opposed to the A/C. IIRC the seals being suitable for air tight (hermetic). Nab a York out of '80s Volvo from a JY. This has been a common formula for OBA setups too. 4x4help.com actually documents quite a few.
ya i am aware of possible leaks. if i have a leak i will grind and keep welding till it holds air but i am pretty sure i will get it right the first time.

thanks for the tip on the compressor. i will keep an eye open for one. i know the old a/c compressors that use to be installed on dodge vehicles could be uses as air compressors and heard they worked way better than the york compressors but then again 2 cylinders is better than 1.

The york compressors are actually better, as they are pretty much self contained. If you use any other variety of compressor, you need to introduce oil into the intake side of the compressor, to keep it lubed up. (leave it alone VW...... )

If you already have A/C, finding a place to put it might be fun, if you scrap your current A/C, mounting it there would be cake.

i don't have a/c. i just have the compressor and a few of the lines. i scrapped the rest. the compressor i have would need an oiler and oil trap but i think the older dodge compressors have a separate lubrication system.

I have always kept my comp air as dry as possible, air tools and plasma cutters do not like water at all, and possibly water in tires.

Two water separators/filters, one between the tank and comp and one after the tank. Is it overkill I don’t think so, I would not like to have to pull the arb diff lockers out to clean them, or worse have them freeze and crack something.

As for mounting the air tank what about putting it behind the driver’s or pass side of the box; sort of diagonal mount to the side of the box. I am guessing that that tank is a 3 gallon and roughly 3’x1’ or so.

Here is the specifications for the ARB compressors.

Upon further looking and a friend pointing out the error of my dream, this compressor cannot be used to properly run air tools. The one that I've chosen in this setup. The choice was primarily for eventual air lockers and air own air source. Air tools was just one of those.... "oh yeah maybe it could!" moments.

So the OP is updated with a note about this.

To properly add the usefulness of air tools, one would probably need to go the mechanical air compressor route, like the York. However, I don't know the specs off hand on that. Research and be sure for your needs.

This is certainly something easy to implement in my system and just good piece of mind. I'll probably take you up on it.

Related question -- are the differentials already under some nominal pressure? I presume they are since breathers are present? I tried to understand if any water actually gets into ARB Locker filled diffs. Moreover, was looking to see if people encountered any water issues on that end. All I found was problems about oil getting in the line, which then over time clogs up the system and prevents operation.

My tank is 5 gallons actually. I'm poorly visualizing your location and what you mean by "box". Sorry.

In my last photo here, my thought was passenger side, right above the Hi-Lift jack.

You can have factory AC and a York 210. It was a bit of work to build the bracket, but it was well worth it.

What would you charge for a set of those brackets?

He ignored you in the other thread, so why would he answer you here?

I have to say, EricCartman has a bad-*** setup. I want to know how loud those horns are.
