According to "Myth Busters" the tailgate up = more drag
perception is a myth. They tested two identical new
pickups and got thirty miles more per tank of fuel with
the gate up. They then contacted engineers at GM
who eplained why. They then put a pick up model in a
tank of moving water and sprinkled oat meal into it to
show how air swirls in the pick up bed and creates a
sort of rolling bubble that makes it more not less
areodynamicly efficient. You can conduct your ouwn
experiment but putting a bunch of trash in your truck
and drive down the road and observe how it swirles
around.;)
