Well my 2016 TEP finally showed up and I traded my 2011 for it. Initial impressions are that more than just a new front end went into the update. Softex is great, and the seats seem much more substantial and comfortable, new dash is a HUGE improvement, stupid orange interior lights are gone, vehicle seems much less "tin can like", its quieter, no brake pedal "squish", I can actually use the backup camera vs that useless thing in the mirror. ENTUNE is a bit of a disappointment, and the sound is not good from the unit. "Party Mode" was much better. I am very happy with the upgrade.
First stop, literally, was the tire shop. Dumped the Bridgestones and put a set of 265 BFG KO2 on. Didn't notice a difference in ride or handling but know I will be happy in the Tahoe snow and off road. One more thing, no more shimmy from the front end from 45-60 mph. Here is a pic
