Two things.
First - The effects of drag are not linear. The faster you push that large frontal area of the truck through the air the faster your mileage will drop. At lower speeds 10 mph will not make as big a difference as it does at higher speeds. Example 50-60 mph = -.5 mpg, 65-75 mph = -3 mpg.
Second - A truck can be geared for MPG but then it will not be great at towing. A truck can be geared for towing but then it will not be great for MPG. At this point I think the manufacturers are about at the limits of decent towing and decent MPG.
