Do your rubbermaids have a way of being closed TIGHT(!), even if it is just a couple of cinch straps stitched together like a skeletonized water bottle carrier? If so, pack them with a handtruck in mind. I've said before, those are one of those things that no one should be without.

As for the truck, I imagine a coach gun and someone watching it would a decent deterent during loading, and foot-cavalry can cover fifty yards pretty quick- quicker if you have a good line of sight. But that's only for loading of gear, admitedly.
