Low Point Drains
This is going to sound like a silly question, but I am clearly missing something on our new coach... The low point drain(s) do not fully empty the fresh water tank?? How am I supposed to get all of ...

If you have a few gallons left in the tank nothing is going to happen. Water freezes, it expands. There is plenty of room for expansion in the tank.
That would depend heavily on the design of the tank. If it is a fully flat surface, you are probably right. Some tanks, however, have smaller bowl-like areas at the drain location in order to help funnel water to that point. In those cases, if water fills that bowl, expansion could cause a crack even if there is plenty of room elsewhere in the tank. A few drops that remain are one thing, but I'd never leave gallons thinking it wouldn't cause a problem.
We don't have a class A, but as others have said, our trailers always had a small spout that could be used to drain the tank. I open it up and drive home from our final drip with it open, that way I am confident that most everything has drained.
