To clear things up:

It is a 10WD - all 10 wheels are driven, with the center wheels being directly driven from the transmissions (like a standard West Coast Drive). It does drive like a 6WD, with only 4 wheels (2 per side) touching the ground at anytime while we're flat. Here's how that's possible:

Wheel 1 --- Wheel 2 --- Wheel 3 --- Wheel 4 --- Wheel 5

Wheels 1 and 5 are on centerline with the siderail of the chassis.
Wheels 2 and 4 are raised 1/8" above centerline.
Wheel 3 is dropped 1/8" below centerline.

With the wheels set up like this, so long as we're on flat ground, only 2 wheels per side can touch the ground at anyone time. However, when going over the bump, the extra two wheels allow us to never worry about bottoming out on the bump.
