But, probably not. You'd almost be best off trying to take everyone's crap and making a boat tail out of it on the back window of the van, honestly. Might get a gain out of it!

The back of those cargo carriers is usually a pretty flat surface. I know people are fond of saying "it would be better backwards".... No it wouldn't, not when a sheer front surface is slamming into the air, causing it to fan out.
Would you say a Prius is more aerodynamic going backward? No, so why say it about any other Kamm shape?
This one might not be so bad backward
