As an aside I also have and tow a small open trailer. Twice I have had 800 lb motorcycles on it and towed. Each time this Ecodiesel still got over 20 mpg towing at my highway speeds. No wind resistance.

how much you guys think a towing wing could be good for? I've heard some companies claim as much as 10% gains, but IRL I'm not sure...

If 10% is what it can gain us then i think it's worth it, it's not hugely significant, but good enough.

I don't know. It's hard to say without some real world testing of different sized trailers.

Now If I were to postulate...I would say for taller trailers, the wings probably are effective in reducing frontal surface parasitic drag. However, you still have drag from the sides, bottom, and rear surfaces. I also have reason to believe that the wing may cause rear suction to increase as a result of increased airflow over the top, but, the net difference with front would still put you in the green.

The back of my trailer is a flat box. Same with my truck that has the cap on it. Both would have a "suction" /vacuum issue that should hold things back.

Another good point.
