Anyone who has ever tested anything in a wind tunnel would agree with my post.
A SUV goes thru the air cleaner vs an open bed pick-up truck.
(For the simple minded, above, the SUV is like a 4 door wagon and the open bed pick-up truck is not that bad once the swirl in the bed is established and the air off the roof hits the swirl and flies over the tailgate (never reaching the bed floor).
A bed cover is better than the swirl / tailgate up, and a hard shell cover is better than a soft cover. A cargo net is the poorest performer as you get drag on the bed, (no swirl) and turbulence at the back of the vehicle.
Lots of data out there, John
Just ONE article out of thousands out there to support my comments:

ps John, you are a LAZY idiot just trying to stir up chit.
