That's exactly right. Imagine a side view of the Dak, or any truck for
that matter but Daks rule, with Rams a close second. Anyway, umm, oh, side
view, Well cover the back 2/3'ds with a cover, now when the air comes up over
the cab and enters into the bed area, it will hit that cover there on the back
part and flow across and down over the tailgate. If there is no cover the air
will be sucked into the bed and be forced back toward the cab where there is
no turbulence and that is where you get your swirling effect that creates the
first drag for the brick on wheels. The second drag is in the same location
as most all vehicles, at the back. When the air comes across the deck lid and
down into the mighty swirl. Does that make any sense at all?
