I drove 4 different crew cab 2016 all terrain models in the past week. 3 were SLT which is what I'd want if I purchase. All were 5.3 8 speed. They were very nice but every one had vibration kick in around 72 to 73 mph. The little decal hanging from the glove box started shaking. It wasn't too bad ...I was just surprised how they all felt the same at the same speed. Then got in my trade vehicle...2014 FX4 and no road feedback at all in steering wheel. I REALLY want a sierra but still nervous. Shake wasn't bad and kept thinking that good tires and balance would make even better. On a side note...anyone know why some trucks are rated for 15/21 while others 16/22? Same 5.3, 8 speed and 3.42.

Thanks for that. Thats what I am thinking but still nervous! My wife has employee pricing which is hard to beat...and i like the trucks. So, I will probably take my chances...after a long test drive. Now just need to find a sales person who doesn't act like a d-bag. Sorry if offensive but really...I have never purchased a GM vehicle and know more about package options than the sales people?

Thanks FL335i..thats kinda what I thought as there didn't seem to be a trend with any particular configuration that I read.

Curious if there is a particular model combination that is most prone to the vibration issues? Crew Cab vs others...5.3 vs 6.2...Z71 /All Terrain vs standard suspension?

New to the site and been watching this thread for quite a while. I currently have a 2014 FX4 F150 (don't hate me). I really want a Sierra All Terrain SLT...every time I see one on the road I stare like a stalker. My F150 has been virtually perfect and I now have 37,000 miles on it. This thread is the only reason I haven't traded for a 2016 Sierra! I keep waiting to read that the vibration issues are fixed for new 16's or at least that the issue is found and all vehicles will be fixed. What the heck GM...I want to buy one of your trucks!
