I was on my way to work a few mornings ago and I passed a brand new Marathon Coach that had front, rear, and side wind deflectors. The front and rear wind deflectors were just high enough where they were above the roof air conditioners the side deflectors were only about 6 inches in height. Does anyone know if they help with fuel milage? Why I ask is my boss has them on his semi trucks (above cab) and they don't make to much difference in fuel milage except when the trucks are moving on flat road for long distances. I'm assuming this will be the new thing for motorhomes in years to come. John

I think they are there to clean up the roof line so those nasty looking A/C's, vents, etc don't show so much.

And if you can afford the coach that I seen then carrying the extra weight above so the dirt don't show wouldn't matter. John

Not going to make much difference whether the wind is pushing on the deflector or the AC itself. Difference MIGHT be noticeable in 100,000 miles or so but barely.

What you see on the sides are the awnings and the front and rear are to make the caps blend in with the sides.
