Neat site.
Thanks!

If you have a later bus with the passenger side airducts in back, chilled air could go there too. You use the existing vent/fan controls, and the heater fan would pull air through the evap and into the existing distribution system. So it is much simpler than add on units like the Behr and the one Larry Chase has that introduce a second and less effective airbox/distribution system.
