So I have had my 2014 Silverado Z71 LTZ for 28 days. I have the vibration problem to and it's no good. I get a vibration at around 68 to 72 and it's quite noticable but when I tow my 20' bass boat it shakes like the front end is going to fall right out of the truck. When towing roughly 4500 lbs it shakes bad, REAL BAD from 68 to about 75 and than it lessens a bit after that but I am not pushing it past 80 towing a boat. I have read about the first 22 pages of this 180 plus page thread and this does not look good. I have the Good year tires and I have 4200 miles on the Truck. Yes I know that's alot for a month but I am a Sales Rep and have a big territory and have been busy visiting my accounts. I have towed my boat three times and I have to keep under 65 to avoid the shaking. I hope to bring it back to the dealer next week but this does NOT LOOK GOOD. Hope GM GETS THIS FIGURED OUT FAST. Thanks
