Thanks thats really good to know. AC is really important to me as I cross the Mojave several times a year I 15 between Baker and Vegas, and I 8 through Imperial valley can be brutal if my AC isnt up to it.

I had been putting my Robinair 15234 pump in the suitcase on the return trip. Last trip TSA held the pump and gauge set had to have friend pick it up at the airport. So if the small Harbor freight pump will do -30 @ 4 feet above sea level Ill pick one up. Sorry to get side tracked from the weak AC problem but thats a big help solved a problem I just ran into.
