Don,
I have built several K2s, and I know for a fact that the toroids do not
change due to vibrations due to portable/mobile operation. I expect the
K3 to be similar. At least one of the K2s that I have built has seen
service in mobile operation in an 18 wheeler for several years, and I
don't believe you will find a more vibration prone mobile situation than
that.

Not just for the K3, but any toroid of similar
construction and mounting.
