I've driven 5k miles now and still feel it. I felt it during the test drive and said I wanted it fixed or no deal. So they brought it in the shop and said it was flat spots in the tires and said they were 100% sure they would smooth out. So like a dumb *** I signed the papers anyway. I picked it up and as soon as I drove home the shake was intense. Drove for a month and still shaking, so dealer replaced the tires. Drove another 4k miles and it doesn't shake as much, but is extremely annoying. It seems to vary more that it did before; still noticeable at 60 mph but seems to wobble at different speeds too.
I really think it's because of those ATMMs/vibration dampers. It does seem as though they function when they shouldn't and don't function when they should. The ATMMs have solenoid activated weights in them, so what if the weights rotate differently from each another? I would think this would make it wobble. Especially with regards to their location. The shake is felt primarily in the driver seat, floor/pedal and center console. There is also a sensor under the hood that picks up vibrations and triggers the ATMMs to activate. See the statement below:
"As the HEMI engine’s Multi-Displacement System kicks in, and sends the truck into four-cylinder mode, an under-hood sensor picks up unwanted vibrations, and triggers these ATMMs to shake their internal weights in a way that’s 180 degrees out of phase with the engine’s unwanted vibration, thus canceling it out and yielding a smooth experience for occupants. This concept is called destructive interference, and it requires tweaking to the ATMMs depending upon the frame length."

There seems to be a lot of unneeded tech in this truck and I feel it's not working as designed. Maybe the under-hood sensor is too sensitive or not sensitive enough? I could swear that my truck rides smoother on ruff roads than it does on smooth.
I need to bring my truck back in, but I already know the dealers response, "this is normal".
