tonneau cover and gas mileage

[mohenry]

For those who have a tonneau cover on their truck, did you notice any improvement in gas mileage? I'm just curious although I'm decided to buy one from 4wheelonline.

Yes, but the data is lost, so I can't say by how much of an improvement.

Yes I would estimate my mileage improved 1.5 mpg on an 09 F150 I installed one on. That was before I discovered fuelly so just a hand calculations at fuel ups.
