I've had the opposite experience than you guys with my 2014 Silverado. I bought a High Country to get the brown interior, and it has had a vibration since new. I originally wanted to lower it, but have decided not to until it's fixed. Strangely enough, I have had a bit of trouble finding anyone who wants to mess with it. My mileage is a bit lower than what has been posted here too. I am averaging 17.0 over the last 1800 miles of mostly highway driving. Must have got a Monday build.....
