Steve,
Don't you just love our Idaho weather? We got 4 inches of snow on the 4th of July in Yellowstone one year.
The joke here is; Don't like the weather? Just wait a second it will change.
We will be getting the second AC this spring. If for no other reasons than better temp control (one end of trailer freezing the other end hot) and that two AC's will not have to work as hard as one.
