4 wheel drive vs. 2 wheel drive

Yes, but even with an uneven weight distribution you're losing pushing power. Even if you stack absolutely everything over your driven wheels, you're probably still losing 10-20% of your pushing power from the weight that will inevitably be over your undriven wheels. Plus you're adding a large design constraint in that all your heavy mechanisms must be in a column over your driven wheels to maximize force.

I understand your idea (though I did gloss that over in my original post, sorry) and it is definitely the most optimal way to implement a 2WD system, I just think that _any_ 2WD system is far from optimal this year.
