I had no idea it could be that large, I had trouble finding images on my own and the ones I did find were not much larger than what I ended up with. The other thread offered no photos, just the tiny diagram images.
I just used my largest scrap left over from my hovercraft elevator project.

On the hovercraft the sheets of acrylic help straighten out the swirling flow from the fan blades.
Back to the truck:
In theory, vortexes will form at the top of cab corners. The tips of the wing stop short of the top corners by about 2 inches. Either this is a good thing by getting out of the way, or I missed the boat on influencing/controlling vortex generation.
