I just got home from a road trip from SC to KY and back. I do have the speedo calibrated. I have 4.10s also. On level ground and downhill it holds 8th fine with the cruise on(I had it set anywhere from 60 to 75). Slight uphill, sometime it kept 8th sometime dropped to 7th. Bigger uphills it would drop to 5th or 6th depending how fast I was going. Pretty much all of the shifts are seamless and if you are jamming out, you won't notice the downshift.Nice! Any issues staying in 8th on the highway or is constantly dropping gear to keep steady? Had a 2010 JKUR that drove me nuts on the highway once I switched to 35s. Put a tuner in and it changed everything. If we drive the JT, its most likely long distance, just trying to see what the characteristic changes are when switching to 35s in this one.
My mileage average for the 1000 mile trip was 18.9mpg
