My thought is why is there no safety overflow drain in the tub to the ground? A $25 drain would save $25k in losses.

I suspect it's because RVs have been built for years on the concept of "self contained". The fresh water tank and water pump would make such a drain unnecessary. So even with more and more folks using city hookups, the manufacturers see no need to change things.
