Your results may vary, but the covert is paying for itself pretty quick. Bigger impact on highway than surface roads, but the overall average is up by about 10%, which is as advertised.

Mythbusters study MPG savings of various bed modifications
the Mythbusters examine the following modifications to a truck's bed to see how it affects the truck's MPG:
Tailgate up (control test)
Tailgate down
Hard top tonneau
Mesh tailgate
No tailgate
Here are the results:
WORST: Tailgate down
BEST: Mesh Tailgate (a little more than 5% savings)
All of the rest were relatively the same, and having installed a tonneau recently I can confirm the lack of an MPG boost.
MORAL: If you're buying a tonneau for the sole reason of improving your MPG you're wasting your money. It seems like there's a lot of MPG improvement myths when it comes to vehicles, but this one is especially bad because tonneau-cover MPG improvements seems so intrinsically plausible. The bed just seems like a massive wind catcher!
This also shows that you shouldn't trust any manufacturer's claim on MPG improvement. With the internet, it's trivially easy to verify their claims so spend 15 minutes before spending a few hundred dollars on snake oil. Perfect example for me is the Throttle Body spacer. They supposedly improve MPG, but a quick search on the web told me (for the types of engines in a Dakota) that this really is a big scam.
Oh, and always be skeptical of perfectly nice round numbers! Many tonneaus claim a nice, neat, and perfect 10% improvement. Yeah, right!
