Yes I've seen that and basically understand the dynamics of it. Thanks again. I see "megacoaches" with the rear air defusers built in to the body work.
We don't drive with any of the RV windows open, but I can see how it would cause a big problem on the back end of the coach if a window was left open.
Thanks again for the info. It's good to see the reasoning behind some of the decisions.
