Build Day 7:
After a bit of sorting and counting, I verified that the shipment included everything I was expecting.
The only real new parts (for me) are the Mecanum wheels, which I plan to use as the main drive wheel[s] on the front (third) leg. Hopefully, with two opposite-direction wheels mounted together, it should act like a powered caster wheel that can drive any direction. I still have to work out the exact size of the feet/wheels.
Tonight I'll start snapping panels together and get a mockup of the body and really start to see how it will look.
