I will close out this thread with a few photos of the replacement air compressor installation.  I know this sounds like rationalization, but I sincerely believe this Kobalt compressor will be superior to the now-deceased C. A. T.  2010A.  I finished the install over the weekend, and it is working splendidly.  It fits perfectly into the oddly shaped space under the entry steps, and will be completely out of the way when cramming junk into the storage bay.

I plumbed this one differently.  I plugged my copper "cooling loop" tubing directly into the compressor tank output fitting.  The other end of the tubing connects to the QC3 filter.  It works this way.  The compressor keeps its 3 gallon tank pressurized between 125 and 155 psi.  The output regulator is set at 120 psi.  The air from the compressor tank bleeds out through the regulator as required, flows through the copper tubing loop, through the QC3 water separator/filter, and then goes to the wet tank at the rear of the coach.  The coach air system stays at a constant 120 psi.  When the compressor cuts on at 125 psi, it only has to pump the 3 gallon tank back up to 155 psi, so it only runs for 35 seconds.  During these short run periods, the compressor doesn't have time to get even slightly warm, so the compressed air in the 3 gallon tank stays cool.  This will greatly reduce the amount of moisture carried in the compressed air stream, and will (hopefully) lessen the workload on the QC3.

In practice, this seems to be working very well.  I have been constantly monitoring the water output from the 3 drain points.  I get a little water out of the compressor tank drain every morning.  I have seen zero moisture come out of the drain on the bottom of the QC3 filter housing.  I have also seen zero water out of the wet tank drain on the coach.  I am confident that the air going into the coach air system from this compressor is at least as dry, if not more so, than the air produced by the coach engine driven air compressor and dryer system.

The only downside to the replacement compressor is increased noise.  However, since this compressor only runs 35 seconds at a time compared to the 5 minute runs of the previous "quiet" compressor, I feel the overall noise factor has improved.  I'll see what the "crew" (DW & Bella) think on our next trip.  If they object too strenuously, all I have to do is turn off the switch on the compressor and close one valve to revert to "normal" coach air system operation for the duration of the journey.  No Problem!  ^.^d

PS: Added info.  If I close the valve and isolate the compressor from the coach air system, the compressor still feeds the retractable air hose.  This "stand alone" mode will provide me with filtered and dried air at 125-155 psi for rapid filling of the coach tires.

This is the one I have, high pressure, reasonable volume, very low noise, low amps. No problem going to 120 on the big tires.

Amazon.com: DEWALT DWFP55130 Heavy Duty 200 PSI Quiet Trim Compressor: Home...

If fits in my (new) bay behind the driver's side rear wheel (along with a bunch of other stuff including a 50' air line). I don't have to take it out to run it, I hook up an air dryer and air line right inside the bay. 

I have the same one. Love it.

For those of you who are interested in this upgrade, California Air Tools is having a nice sale.  Their factory outlet store is  closing out the discontinued model 2510STP and the price is reduced from about $278 on Amazon to $149 with free shipping and no tax outside of CA.  The unit is new with the full warranty but is blemished.  We used to call these "C Stock" items in the audio video business (scratch and dent).

I'm ditching my 82db Porter Cable "Wake the Dead" model for this quiet 60db puppy.  It outputs 2.35 CFM@90PSI and is a twin cylinder unit.

The CAT compressor that Mark D mentioned is only 120 psi max which makes filling a coach tire pretty slow.  Should be OK for just leveling and air bladders and other aux tasks. The Dewalt mentioned before that is 200 psi max and is  smaller and lighter.

That's a good point, Roger.  Also, I had forgotten that Chuck's CAT compressor motor burned up (see reply #20 above).  I rethought this and called CAT and asked to cancel the order.  They said no problem if it hadn't shipped so we'll see what happens.  If indeed it cancels I think I'll go with the Dewalt you mentioned.  It's 70db but that's less than half as loud as the Porter Cable we currently have.

Finally decided to get a aux compressor. I only need 85 front/80 rear, so this works great. BTW, it takes about 4 min to add 10 pounds to each tire. I like the dual head chuck, liquid-filled gauge . The locking chuck version might fit the inside duals, but I did not get it. Power Tank - - Powertank.com

That sure is a purty blue air hose!
