Here is the latest version, opened up the valence a bit and added foglight covers.
Running cool so far (185F to 190F typical) but the weather has been cold. However it appears to run cooler than it used to run with no grill blocks, at 195F.
If I stay under 45mph, I can run mid 40's mpg no problem, with moderate hypermiling (no EOC). With EOC, low 50's are achievable.
