I can personally attest to the fact that the Power Poles will stay connected
in a mobile installation under some rather extreme stresses.  Check out the
Jeep section of http://www.JeepGunner.com and this article specifically
http://www.jeepgunner.com/jeep/mfj1.htm.  That Jeep hit some very extreme
trails (Moab and other places) and very rough dirt roads at speed from time
to time.  We never once had one disconnect on us - they always stayed tight.
We used Power Poles at multiple points for the overhead mounted radios as

The one concern I have about Anderson PowerPoles is that they are not a
positive locking connector. They depend on friction to stay connected.
Without some sort of lock, they could vibrate apart, especially in a mobile
installation. Don't get me wrong--I love PowerPoles and use them in other
applications. But they do have limitations.

For my mobile installs, I use a Blue Sea Systems blade fuse block. 
They are available with either 6 or 12 individually fused circuits and they
use screw terminals for a positive, vibration resistant connection. The
block comes with a cover so your connections are protected. And the design
makes for a low-profile installation without wires sticking out
perpendicular to the panel on which the fuse block is mounted. You can buy
these fuse blocks from West Marine (on-line or at one of their many stores
around the country). A little pricey, but I've never had any problems with
