Tim,
Thanks for your insight. That really helps me sort out what is a real concern and what is not. I was thinking about braking and if the shade would be flopping forward and back.
If your coach is handy, I have one other question that would be a help. How wide is the flat area on your A pillars that the shade rides on (mine is 1/2 inch) and how much overlap is there of the shade on that flat. That info would help with a little planning if you get a chance to take a couple of measurements.
