OK, I added my truck. Since the photo above I taped shut the lower air dam hole, the light holes, and half the bumper hole. Only half that hole is shrouded into the radiator.
Did another big trip, 20.3 mpg, to visit my dad. More city than the 22 mpg trip, to visit my mom. He liked it a lot better than she did: "Cool! Scientific investigation!" vs. "Oh. We'll take my car to dinner." Can you guess who's the engineer?
That flex is with swaybars in place and overload springs, too. I figure it's ok. What I need is some more up travel; it bottoms out after maybe 3".
The next few days will show whether it was really worth a damn aerodynamically. Either way, tomorrow my aero cap is turning into a storage shed
