About a month ago I traded my 2016 Limited for a slightly used (14K miles) 2019 Laramie. This is the first Ram I have owned that has the 3.92 gears, all my other trucks had the 3.21 gears. In my opinion it makes a huge difference because the transmission is less busy down shifting at cruising speed going up a slight incline. I purposely bought a truck with the 8.4" screen because I previously owned one with the 12" screen which turned out to be a big headache. I did upgrade to embedded navigation though because I am not a fan of Android auto or Apple car play.
