It's worth noting that not only must you vent such an A/C unit to the
outside, but you must also leave some kind of window or other space open for
fresh air to enter the van at a rate equal to that of the vented air, lest
you cause a vacuum and then your eyes pop out of your head a la Total
Recall.

Okay, well I was serious for a minute there, anyway. I have a Sharp
roll-away A/C unit in my music studio and I have one special wall vent
designed for exhaust to the outside and another vent designed as a fresh air
inlet. Yes, that means that hot outside air is always coming into the room
to be cooled. That's one reason the portable devices are not very efficient.

Now back to Vanagon content re: keeping cool. If I could find a single
replacement screen for a sliding Westy window for $30 or less I'd be really
happy.
