Yet another Air Dam/Spoiler/Airfoil thingy
Since we don't have enough threads on this already: I decided to make one, the goal was to reduce wind noise which was more with the camper on than off. Also wanted to reduce the bug count on the c...

Update:
I added a stiffener to the lip of the valence, 1/4 x 3/4 aluminum fit behind the molded lip nicely, just bent it to shape screwed through to some tapped holes.
Second 900 mile trip from home to Anacortes, WA, about 900 miles, this time with the wife. She immediately noticed the reduction in wind noise. The valence held its shape. From the rain pattern, it seems to be different when it stays in shape. The camper bulkhead is dry, even in fairly heavy rain. There is an arc of wet about 12 - 18" behind the valence on the overhang, this seems to be where the jet of air squeezes between the windshield and the valence. The V of water from there back where the valence folded is gone. I should have cleaned the bugs from the bulkhead before I started this trip, can't tell if that is different because the old bugs are still there.
Fuel mileage last trip was reported as 12.0 mpg last time, 13.8 mpg this time, but I think most or all of that can be accounted for by better weather conditions. Last time persistent headwinds, sometimes quite strong, this time more even handed and not all that strong. I don't think mileage has been affected significantly either way.
