Congrats. I had been watching that thread with interest over quite a while. My 3640RL doesn't seem to have the same problem, but then again with 2 AC units and given the relatively low temperatures we 'camp' in, I wouldn't expect to have trouble. Nevertheless, I now know what to do if I find we are not getting sufficient cooling. Thanks.
