I don't think so, not where mpg's are concerned. I've had both. I also watched my mileage with the bed naked before I got them.
2008 silverado cc 4x4 5.3 with hard fiberglass tonneau
2013 silverado cc 4x4 5.3 with fold up tonneau
2015 silverado double cab 4x4 with shell
Not much difference in any of them. For one thing the shell weighs a lot more.
