I can haul heavy stuff.  Its just time consuming, plus the 2 hours (+/-)
of road time.  Also, its going to take time to move one compressor in
and the other out.  I am considering an "outdoor" compressor closet, and
plumb in both compressors together.  Just have valves to shut one off
from the distribution lines and only turn on one or the other.

Might see about some sort of transfer switch so I can't accidentally

It would be nice to get the compressor noise out of the back shop.

Check valves in the lines and a double throw power switch (3 ph

Can someone explain gladhands to me? I'm wondering if they would be
better than the garden hose couplers I use to flexibly connect and
reconfigure my 120 PSI max air system, in which the air may flow in
either direction. A Net search suggests they can be dangerous to
handle because they don't close automatically when disconnected.

If I could get all the tiny little losses eliminated I'd be tempted to
use both tanks for air storage, and just periodically switch which
compressor fills them. Then even if a compressor failed it would carry
the air seals for hours.
 
I also considered some sort of auto backup.  The easy way would be to
set the backup compressor to switch on at a lower pressure, but there
are a number of small issues that could cause both compressors to run at
the same time.  That's power I do not always have.  I never intended to
have a working machine shop.  This was just supposed to be a warehouse
for my contracting business.  I only have a 100 amp sub panel feeding
everything.  I know.  I know.  Upgrade the sub panel.  The house only
has a 200 amp main, and my wife wants to run electric demand heaters.
I'll have to upgrade the house main first.

  Can you set up a relay lockout that whichever compressor is running
will cut power to the other ? An "or" gate type setup .

 Just a pilotted (monitored) relay with the pilot on one in series
with the coil of the other
