I have done this too.
Put unit in luggage rack, and covered with canvas to top.
AC blows in screen.
Very simple.
Works well.
The only small problem is moving it down when I move.
An older, now off list member told me this last summer.
He had good idea's

Good Morning,

Fred.

Owen, what AC unit was it that you got from Walmart? And how did you
mount your unit on your vehicle? Pictures?
Thanks,

A quick solution for me is a mini portable window unit from Walmart
($60.00 with remote) stowed in the top bin. Simply lift it up on the
ledge and it blows into the screened window. Thermostat controlled and
whisper quiet. I found this solution in the archives. The guy that
suggested it also suggested sewing a closure to keep the cold air in. We
used a blanket and clothes pins to complete the Jed Clampett affect. We
were very cold in August last year.
��A nice refinement (also from the archives) is to build a hanger to
hook into the top stow bin and hang it down into the driver or passenger
window with a nice cut out to fit it to. Maybe this summer I will add
that refinement. Here in Houston it was 98F in the shade at 10:45 this
morning.

Subject: Portable Air Conditioner for Westy?
I know this subject has probably been covered many times, but does
anyone know of a good portable air conditioner solution that works in a
Westy
when
parked at a camp site with a 110 hookup? Deep South summer time camping
is
BRUTAL!
The humidity has already been relentless this year.
