Tailgate up, at least from the videos.

With the tailgate up you're leaving a shorter wake -- the gate catches some of the turbulence from the cab and puts its momentum back into the vehicle.

ETA: "Shorter" as in vertical height. The trailing length isn't as important, it's the perpendicular area of the dead wake that "pulls back" on the vehicle.
