We live in Florida, and travel all through the southern states. We attach a blanket from the overhead bunk and let it fall to the floor behind the driver and passenger seats. Just this blanket, closing off the rear of the coach from the cab really does insulate the cabin for a much more comfortable drive. It keeps the cool air in the cab, and the heat from the rest of the coach out of the cab. Cheap, simple solution for comfort.

We "discovered" the great idea when we picked up the new motorhome on it's maiden voyage from Florida back home to California.
I predominately did it at night, so that I could drive without interior windshield reflection from the kids playing Xbox on the television, and the coach interior lights while in transit.
But, I did notice that the chassis/dash A/C was much more "efficient" for me with the blanket in place.
