If I was that worried about my fuel economy, I wouldn't have bought a Titan in the first place. My bed cover is for keeping cargo dry and secure, and random jackasses from using the bed of my truck as a public dumpster when I'm parked at the store.

I have to admit that highway driving with a cross wind has a lot more pull with an open bed than it does with the cover closed up.

Oh, absolutely. Cross winds have a far greater influence on my truck when the bed is uncovered versus when I have the Undercover tonneau on it.
