Hi reporting to what I believe is the correct thread for my issue:
From what I'm reading there is not much of a solution for the vibration problem. I have 2014 6.2l with the max trailering package as I tow a 8000lb toy hauler. Truck tows great but the vibration when towing is getting worse. I'm not sure if this is the same problem as mentioned in this thread but as you can imagine when towing you put a big load on the truck - this is making the vibration bad.
I've already brought the truck in three times to fix problems and with only 6000 miles on it I'm disappointed to have to bring it in another time.
