Yes, that last bit is the most significant disadvantage. Until battery/ fuel technologies are improved, these mules will be a logistical nightmare, in the sense that for their usage in the real battlefields, and for the lengths a live mule train can cover, the fuel needs of the robotic ones will be gigantic.
unless they are so cheep to make that the become essentially disposable.
So we should just abandon inventing new stuff, I guess. Technology has never resulted in any useful products.

I imagine the same argument was used when the military first started using trucks.
