Tonneaus
Our new truck doesn't have a tonneau cover for the bed, and we're thinking that it would probably improve aerodynamic performance (and mileage) if it did. Does anyone have experience with adding one ...

I have had tonneau covers on pickups for 30 yrs and have never seen much improvement on mpg.I like them for security plus on occasion I can get out of hauling someone's items.
