Does your commute have any hills at all?
I live in an area with small to big hills and my mpg was at 14 for a 10 mile trip. It has gotten better at 15 to 16 but that's if I'm extremely light on the pedal.
I did notice that in areas with no elevation changes in the city, I was getting 19mpg...
Yea my tailgate is the same way. One side I could fit my finger while the other side was flush. I tried to shimmy it but it wouldn't budge. 600 miles later and I've used it plenty, it kinda balance itself out.
I think it needs to be tuned. It also depends on the genre. I wasn't getting much bass from my usual songs but then I played "trunk by phonk killer" and man the truck was booming at loud volume with no distortion.
Pick songs with heavy bass and you will not be disappointed.
I got the bronze oxide. The bronze shines on sunny days. In the mornings it looks dark green. I got to see it when it got there and it was really dirty. The dirt actually made the bronze stand out. I quite liked it dirty.
A month ago on youtube I asked JRdagreat a toyota master diagnostic technician if they had gotten word of the tacoma grill shutter going bad and he said no, but they had been getting some tundras with the same issue.
