I can tell that this is going to be a GREAT build! I have slowly been collecting parts (and trying to work out the mechanical bugs) for a similar build, that I have not started yet. Silvio and I even had some discussions about him building the armored cab version for anyone else who'd like to build one as well. The best tires I have been able to find are from Lego, but yours look MUCH better - where did you get them? One of the biggest hurdles I see is how to get matching gear ratios if the front axle is powered, and the rear set of axles are driven by chain from a small set of sprockets. The best thing I could think of was dummy-ing up the front axle so that it wasn't actually powered - which kind of defeats the whole 6x6 idea.
