when I was at the wall mart buying the fan I was also scoping out thier personal ac units.I think they were less than a hundred bucks. I thought about stuffing one of those in my canopybut went with the fan instead
Would've had trouble anyways. You'd have to find out a way to route the condensation from the window unit into a drain or outside. Not to mention those copper cooling coils on the unit would corrode up from the salt.
