Rear exit has been addressed somewhat (aerohead), but I don't remember thread topic or title. Probably on one of BamZipPow's threads.
Partial bed tonneau (plywood would suffice) extending from tailgate to barely past the midway point to cab is a cheap upgrade. Again, aerohead.
If you're a genuinely good guy, contact ChazInMT for how to take a profile photograph of that pickemup, and get him to draw the curve superimposed. Use it or not, but you'll better understand aero lid covers.
Aerohead has also talked about tapering the body exterior inwards from cab to tailgate. Doesn't look like you're afraid of much.
Take in the full array of what can work for aero. Subtle changes might work wonders.
And, Polymetal. (With Da Beard Free we're gonna find a way to make that Miracle Metal a holy sacrament for initiates. The old Hip Eye picked up on the vibrations of that stuff and damned if the waveform didn't finally hit Tejas).

Thanks for the input!
This pic will better show the height. This is after driving up on ramp for my 4 post hoist around 6". I do plan on extending the airdam to better cover the tires. I really want to make my own out of metal with maybe a rubber or plastic lip so no damage will occur if a speed bump etc is too high.
Once I finish testing with the E30 fuel that is killing mileage I will switch back to 91 and then start tweaking more for MPG. I am planning on a trip to southern california at end of this month so hoping for more gains by then.
This truck is a 126" wheel base. (stock is 129")
Back to the 1/4 mi this weekend to see what if any MPH the tweaks add.
