Greetings from Southern California !!

I'm about to take on a Dash Air Conditioning investigation / improvement project.

I'm aware of some of the options and am closely following the new dash AC systems being installed down at the Coop (Thanks for those postings Jim).

Has anyone retrofitted the newer model's under dash vents to a system that didn't have them? I'm envisioning that it'll require the creation of an opening through the firewall and into the air box. And then the retrofittting of some sort of sheet metal panels to route airflow to the new exits.

Or does such an opening already exist and the "max air" underdash vent assembly slips into it?

Or is the addition of an underdash "Vintage Air" evaporator a better solution? How loud are these aux units?

And... might anyone have an underdash vent unit that you'd be willing to sell. I expect they're only available from donor coaches...

As always, thank you all for the wealth of information posted here and thank you in advance for your comments and suggestions.
