Adding auxiliary air

[Don Bradner]

I have no need for 1, 3, or 4, but number 2 is a big one for us. I never like to
sit in an RV Park with an engine running longer than necessary, and I very much
hate listening to low-air buzzers!

I start my departure morning (which is almost never early!) with block heater
and air compressor. That combo means that I can release the brake and drive away
as soon as I have oil pressure.

Items that are also important to us where the compressor is handy are: Dump
valves (frequently, due to washer/dryer) and oil top-up (infrequently).

In short, the aux compresson is one of the many things I didn't have in my SOB
that I greatly appreciate in the Bird!
