I've done the same thing. Plus a couple ideas that might work for others
as well. I've mounted one of my compressors above the garage door on the
inside wall. How I got it up there is another story. Also I've plumbed
both compressors into an 60 gallon tank from a water heater. The tank
is also mounted above the garage door. This leaves one compressor that I
can roll out to wherever and one stationary in the shop. The extra air
tank helps reduce the load on the pumps.
