My Isusu PU is one of those that has a drag with the tail gate up. I push through a big drag area going from 45 to 50. When I have the bed filled it just flies through that speed. With the tail gate down I don't get that drag spot but it doesn't feel as zoomy as when it's filled. Some day soon I plan doing coast down tests to get some numbers to see just how much differents there is, I'm also planning to make a aero back to test too.
oh also I've not felt this drag driving full size PU's and have not driven other small ones to campare too either. So I can't speak for any thing other that this one, but no hard data to show for now.
