I forgot to mention, my other goal was to make it fairly unobtrusive, and easy to remove. As it is it only obscures maybe 25" (I meant to say 25%! Big difference, sorry) of the top of the view out the back window, which is not bad, and it swings up with the hatch.

I may add sides of some sort that start from the most aft point and taper down to nothing near the bottom of the back of that van. Maybe heavy duty sailcloth or something that can tension and still be easy to put on and remove.

I like the idea of the diffuser fins on the bottom, but that would be a later project...
