John is right, I also use one of the Walmart small
window units, cost $78.00, made a little wooden stand,
with a support leg, it fits right in the drivers
window, tip it back a little so the condensed water
runs to the outside instead of inside, ask me how I
figured this out(wet seat). I used scrap wood to make
the stand so the total cost was $78.00. Works great.
