Im basing my improvement assumptions off of Big Dave mostly to be honest.
He saw 3/4 of gallon mpg improvement with airdam, possibly .5mpg improvement with mirror delete/folding. I don't know if you seen the 2008-2010 mirrors on super duties they are HUGE! when I wired them in it helped immensely with visibility though lol....
So If I could squeeze a solid 1mpg off of air dam and folding mirrors in (maybe adding angled deflector) then 1mpg from tonneau cover, possibly 2 off an angled cover that would bring my 17.7 current best to a whopping 20.7 lol....
for me though diesel is $3.29-2.59 on average a gallon with my 13-isk k commute.
17.7mpg=2423.73 annual fuel cost
20.7=2072.4 annual fuel cost
Those are very simple calculations but I could save more as the diesel tax is going to increase three more times until 2020 lol. I have plans to move back to Idaho within a few years but for now this gives me something else to work on.
p.s. Anyone experience with turbo modifications on a powerstroke not for power but for fuel economy? My current GTP38 is stock but I bought what is called the wicked wheel 2 compressor wheel. I tow a lot and I get what called turbo shudder and it can cause damage overtime. A few companies came out with a new wheel, different fins, aluminum and it equates to:
5-6more psi boost, smoother/quicker response, and a little less egt's esp when I delete my EBPV valve on the turbo and add the high flow outlet. It causes very bad mpg in the winter for me
