Yes I just noticed this yesterday, not just bc I was driving 40 mph, but was driving while its was a little windy, not really sure what was causing this but definitely annoying.
Just purchased a 2020 Custom, it's a beautiful truck, but several days ago I noticed that I dont have 4 lo, "sigle tranfer case" anyways not a huge deal but how well does the "tearrin mode" mimc 4 lo?
