When we bought our coach the one thing I did not think of until the last minute was the A/C. Probably like a lot of people, we shopped and bought in the winter so the A/C was not really even a thought. Then I started reading forums about the coach we were interested in and found that a lot of coach A/C units just don't cool well in intense heat. We then looked for a coach with 3 units. But even in the HOT HOT summer of the southeast we sometimes have to use the Relflectix on the front windshield to keep the coach cool enough. It is just hard to cool sometimes. The Relfectix keeps the coach a good 10 degrees cooler, I would estimate.
