But those webbed tailgate thingies have GOT to increase drag.

Don't they???

OK, Following up on on old thread.

I spent the day working in an automotive wind tunnel today, and I thought to
ask the operator if he had tried tailgate up / down in the tunnel.

He said they did a bunch of tests on an F150 and found that a tonnau cover
was best, a cap was nearly as good, tailgate up was better than down (I
forget if there was a difference between down and removed) and the web
things were the worst.

With the tailgate up, when they used smoke, the smoke would go over the roof
and then come down and touch the top of the tailgate.

Jeez, there goes my excuse for not fixing the broken latch on the
tailgate... I hate it when that happens...
