Another out of city loop and back today. 28.4 mpg on the trip out(up hill) at 55 mph top speed, sadly I had 7 stops I was hit with flakey lights and just horrible timing. On the trip back the average picked up to 34.3 mpg at 55 mph and only had to stop at 1 light on the way back. So far the pattern in fuel economy on that loop has been fairly consistent other than when I choose bad time to go and get caught in traffic.

So I am a little concerned this truck isn't going to make my target 30mpg at 65 when I am averaging about that at 55mph. I am not sure mods are going to help me pick up the difference in FE. So it is time to just get on with the mods and lets see if I am going to hit my targets or not. Tonight I installed the tonneau cover on the truck. I have been waiting for some time to get that on the truck and it feels good to finally have it on. I will make some runs this week on my out of city loop and see if the FE improves.

Next weekend if time permits I will get my air dam mod done and see how that affects things the following week. I have to get some materials for the grill block soon. Right now based on what I have seen from other peoples mods it looks like the best case scenario I can expect between the cover, air dam, and grill block looks like I might make 29.5 mpg best case at 65mph. Not quite what I was hoping for so I will just have to be patient and see what happens and then decide the next steps once I get there.
