That fast back crap won't help a bit, it will only add weight. A pickup truck already gets that effect by the turbulant air behind the cab with no extra weight.

If you want to better the aero in the bed area: use a tonneau cover and put a 6-8" piece of aluminum extending the roof off the back of the cab and tonneau cover over the tailgate. that should get you up to 2mpg at highway speeds with minimal weight. A truck cap with the extension off the back would also do.

Plug any holes in front, lower truck, add a front air dam, remove trailer hitch and replace rr bumper with roll pan, remove all extra weight. Get smaller mirrors. Use under-drive engine pulleys. tune up the truck. Increase gearing
