Lego 4 x 4 with Differentials

This is a vehicle which was thought up as a challenge... What vehicle would be able to traverse rough terrain and be geared down to climb some steep hills? I designed a vehicle in which all power is diverted according to need by the three differentials. As it turns out, this is actually a negative point considering that if one wheel loses traction, all of the power "leaks" out through this wheel. This will soon be remedied by creating a 4 x 4 vehicle with no differentials -- i.e. constant, 100% power to all wheels, all the time.

Here are some images: (with explanations)

I have constructed a list of graphical instructions with LDraw / Ledit. Here are the LDraw Instructions instructions..
