Oh - Great....Something else to add to the "s--t to worry about" list!
3000 rpm seems to be my favorite rpm - running around town and on the freeway 75+ in 5th!
I don't drop much below but normal use I tend to be 3000 to 4500.

In the twisty bits I tend to run 4500 to 5500.

I had this issue for some years
Mine is a 2,7 my 2000
Purchased in 05. First thing on the fix list was a new motormount.This did not cure the vibrations.
At that time I noticed that changing the way the rear muffler was hanging changed the amplitude of the vibrations.
Anyway, I replaced the dmf but no improvement at all and learned to live with it for some years.
A rear cat delete was done and vibrations moved up to the 3400 rpm range, out of my cruising speed.
Still a little bit annoying so I devided to do a second motor mount job and found that there was a later version available, even softer rubber. This was the cure but instead I got a feeling that the engine is moving around in the back when I am a little bit inspired.
I consider my engine to be well maintained and in good condition with 10k km on the odo, us import...
But the 3k rpm vibration is there, only hidden by a rubber mount but I gues this is the same for all engines, amplitude is just depending on the internal tolerances.
