Dual Air

[Tim Hogan <Thogangoatx@xxxxxxxxxxx>]

I have a '63 with dual air that originally came from Texas.  You can cool
both the front and rear seat quickly without freezing either end too cold.
You get even cooling without excessive draft.  And it cools down very
quickly too.  Takes a lot of truck space thou.
Rear air controls consist of fan switch only.  Relys on compressor to be
switched on with the standard front controls.  you could then run the front
on low fan and mix moderate the temperature of the front air and run the
rear air on hi rear fan if you wanted to generate most of the cool from the
rear for some reason.

Rear air blows more gently also otherwise terrible draft on the back of your
head or neck.  And yes, the rear vents sweat and eventually ruin the "cane"
covering onthe back deck.  I had to replace it.
