Thanks for posting. I think I would like to do this in the future. What size is the unit and/or part number? Are you just using one or would a person need two, front and back. I have seen many other coach owners add these also. Really looking to see if they really are the way to go. Wonder how big one needs to go to cool down enough, driving down the highway on a summer day. That seems the most extreme situation.
