First off, sorry to bump an old thread.
Second, I've searched around and haven't found much about people mounting a PTO style compressor on a bus. Has anyone here done this?
Yes, its most likely overkil but my skoolie is still in the dream stage so why not dream big?

Bumping a old thread like this is good.
There is no PTO on 99% of buses.
Also, there would be no advantage to running the compressor off a PTO vs off the front belt system. If you need more air volume, run two compressor heads.

I built a York on a street legal rock crawler about 20 years ago. Worked awesome! I even used a pressure switch just like the ones on shop air compressor so it would shut off and unload the compressor when air was built up and then it would kick back on when the air in the tanks dropped down. I had a couple of $7 air tanks from Wal-Mart tucked up under the bed.

$7, Walmart, and air tank......I'm pretty sure those words aren't supposed to go together!

I use these for the show trucks I build. Each truck gets its own compressor and is tons cheaper, quieter, and puts out equivalent or higher air than ViAir or Air Zenith, which are the only two brands of electric 12 volt compressors ill even touch. They are capable of very high psi. I ran the air system on my truck at 250 psi and it would build from 0-250 in about a minute and a half on two 3 gallon tanks.

Did that ever come to fruition? How'd it work out? Had considered it as well.

Need a way to differentially pressurize the tank, to avoid hand grenading it.

Thanx for bumping this thread back into the light!
One more thing I didn't realize I need, but ought got have...

so i take it this is for those without air brakes or air suspension? those Bendix Air compressors factory installed are 11-17 CFM depending on the model.. more than enough to run most air tools

Is this in response to multiple reservoir setups, or am I missing something? Or are you referring to the notion of a positive pressure water reservoir? My assumption was that you would pressurize to drive water to your highest outlet, in respect to your systems pressure capacity.

Having found this old thread just this evening, I respond respectfully: I believe that premise was in the OP. Personally, I'm here because I have hydraulic brakes, and own only 12v compressors
Not sure which periodical maintenance item I would prefer - air brakes, or belt-driven air pump...

Responding to your truncated quote regarding water pressure.
Without some way to maintain low head pressure in a fresh water vessel, it will quickly pop like an over-fed tick.
And ain't none of us wanna see that.

An on-demand, engine-driven compressor would be a handy thing to have on a picnic..!

direct line from the compressor with a regulator set at 30 lbs or what ever pressure you desire to your water tank would provide reliable constant pressure at the tap - you could still have decent water pressure as your air pressure gradually bled off when you ran the water for quite a while before you had to run the engine again

FNG here so rather than make a typical intro thread first post (I'll get to that later) I'll start here. Stumbled on this topic and was curious about the oiling and hadnt seen anything mentioned in the thread about how to service these. Searched a bit and found this PDF and had to share.
***Had to break up PDF due to forum file size limits
