If anyone thinks that adding an air deflector DOES NOT help is delusional. Air going over a trailer vs. slamming into the top of the trailer is a real thing. How much? Can't say, but it's a reality.
How much? Got any data?
No bug splatter on the front of the trailer means the air is being moved up and over the trailer. Also the .5 mpg improvement says it works as well!
I don't see how anyone could detect that small of a difference. It would take a precise fuel consumption measuring device and identical driving conditions. I see huge difference merely due to traffic, wind direction, etc.
Well 3 years and 20k towing miles after its use shows that it works. I did the same trips big before and after and there was always that .5 difference. Sure sometimes it may have been less, sometimes a bit more but it always averaged .5 better with it.
