I beg to differ.
U-Haul and others regularly rent trucks of that capacity
to "the rest of us".  I have gone on a few "raids" myself -
(for old computer equipment, etc.).

I just called U-Haul, and their price for one way 
Albuquerque  to L.A., for a 24 ft. truck rated at 4 tons,
is $390, (they allow 4 days).  That is probably
a typical price.  No special license is required,
and a 24 ft. truck is not scary to drive (a breeze).

I'm retired, and could participate, probably wishing
to put a couple of units in my sedan for a trip
to the S.F. bay area  - where others would likely
enjoy the fun also.  ("Big boys, big toys?")

Packing for such a ride and handling is interesting.
Be a shame to wreck such equipment with casual handling.
A good thing to research well!
   - locking for shipment
   - vibration/acceleration sensitivity
   - attitude, etc.

> 2) Re: testing for noisy units

    I would bet that NONE of the instruments are sufficently
    noisy for us to test.  Our typical enviroments are so many
   db more noisy that of a reasonably quiet site.
