Probably not silly one bit. I'd guess a slightly less goofy and similarly
effective approach would be a lateral fin on the back of a hard tonneau (or
stiff soft tonneau). I believe the airstream comes over our cabs AND over an
eddy just at the rear window, then smooths out as it drops toward the level of
our bed rails, then down over the tailgate. I think the trick would be to
catch the flow rear of the eddy with a fin and direct it up over the gap 'tween
truck and trailer. I think a box trailer and finned cap would get the same
thing.
I think a thing about "socks" might be that flexible surfaces like canvas tops
deform in wind streams, causing troublesome turbulance.
Anyhow, send us pictures.
