Just filled up, 15.28

Found out last night I need to modify my design.
On the way home my buddy says " hey, that thingie on your van is bent"
Turns out around 65MPH, it starts to bend back and by 70MPH the right side has fully flagged back in the wind.

I think a horizontal brace 2/3 way down with 2 kickers to ___________ are next.
That way there will still be some give at the bottom.

Anybody else have this issue ? The truck with the conveyerbelt dam (Dave?) ?
Darin, did you have this issue with yours ?
