couple more pictures after getting it washed:
I could lower the rear some more for less rake, but I'm content for now. Also discovered the truck's first door ding. Starting to think this thing is cursed. It's only 1/2" long shallow crease in the driver's door. Easily pressed out, but still maddening. Goes in to have the bumper cover ceramic coated and dent fixed on Monday.
Took a 600 mile round trip this weekend. Loaded out with 5 passengers, AC on and running 75-80, averaged 22.5 mpg on the way down and 23.0 on the way back. Much better than my 2013 would have gotten. I was impressed.
