Adding an Auxiliary Air Compressor

[Ryan Wright]

Hi John,

I asked about this last fall and generated a lot of discussion on the
topic. Here's what it boiled down to:

The factory air compressor is made by "Gast". It's 110 volt and I
think 1/3hp was the power offered. Someone told me it takes 30 minutes
to air his coach up with that compressor, but a 3/4hp model will do it
in 5 to 10. I'd love to hear confirmation on this from those who have
aux air installed - how big is your compressor and how long does it
take to air up the coach?

I want to add auxiliary air to my coach and I intend to use a 110 volt
Gast compressor if/when I get to it. These look to be $500 - $800 new
but they pop up on eBay occasionally for much less.

Problem is where to mount one. You'll have to put it in one of your
bays, so you'll be losing storage space. I've not yet decided if and
where I want to lose such space, thus the reason I've not taken on
this project yet.
