All three pickups (a Toyota SR5 and two Ford Rangers) I've owned got better fuel economy with a standard topper on than with just an open bed, typically about 10 % better.

I've never tried a tonneau.

With my present truck, I did try it with an open bed and the tailgate on and off (not down, completely off). I didn't notice any difference in FE, though I probably wouldn't have noticed anything less than a couple of percent difference.
