Vibration issue solved.  One of the engine mounts was installed incorrectly.  It was not properly centered and seated in it's hole when they bolted it down, which pinched the mount to the point where the metal on each side of the mount was rubbing at lower RPMs.  As the RPMs rose, the torque rotated the engine enough to separate the metal-on-metal contact.  Turned out to be a very easy fix that cost a lot of time and frustration.  Happy to have it all worked out now.

You're headed for many years of happiness. 13K miles and counting for us, not one drop oil on the ground, and engine clean as a whistle.Lots of power.
Even with th investment of the engine, you have a steller coach.
You might read my post about oil if you haven't. Stay with straight mineral oil in my opinion. Delo seems to be the favorite. Hopefully they won't go to blended.

Excellent read Doug. Verifies what I thought.
The whole deposit thing is what's important with Cats. Probably why they have ring issues. That is why I change my oil so often.
With the Cat HEUI pump, the oil condition and velocity is really import, I think more so then the Cummins.
Lastly, I truly believe blends break down too quick, hence the heavier oil usage.
Interesting  they try to sell you on extended oil changes with blends.
