Low Point Drains/Winterize Leprechaun 220QB

Since there seems to be a bit of variation in the setup, and it took me a while to find things (my PDI was not as thorough as it could have been), I thought I'd post some pics on my setup. May be applicable to the similar Coachmen models too (or not).
While there is a big sticker that says "Low Point Drains", it took me a while to realize I needed to remove a grill to get to them. Anyway, here goes. Please correct anything I've got wrong, this is my first time with this RV. I had a houseboat for a few years, with a similar setup, but things were a lot easier to find on it. I used compressed air to clean the lines. The first pass I did not find the low point drains and slow purged via the pump and air, removing the hot water tank plug. Have not yet found where the water pump itself is hiding. On my houseboat I would disconnect it.

Outside service panel. Blue valve is in city water position. Used this to clear all the faucets, outside shower and the 2 left low point drains.

Blue valve in tank fill position. Used this and the right low point valve to get all the water out of the tank.

Port under the bed with access to the water tank. Sorry, it got turned 90deg ccw when I uploaded. Don't see how to correct it.

Shutoff valve for the water tank? It was in the open position already. Also turned 90deg ccw.

Hot water tank bypass setup. You remove the drawer under the stove to get to this. Also turned 90deg ccw.

Grill under the stove, hiding the low point drain valves. Two Philips screws to remove.

Low point drains, closed position. One on the right drains the fresh water tank.

In addition to opening the hot water heater bypass valve, you need to turn off the cold water valve on the line going into the hot water heater and turn off the valve on the hot water line coming out of the heater.

To my way of thinking, that should be done after the water lines and the hot water heater tank have been drained, and before blowing out or adding anti-freeze to the water lines.

Don't forget to blow out and/or add anti-freeze to the external faucets and the black water flush line. Don't forget adding anti-freeze to each drain including toilet, external sink and shower. Lastly, be sure the holding tanks are empty. Some people recommend adding some anti-freeze to either the black water tank (to keep things liquefied), or even both tanks for safe measure. (In theory, if there is nothing in the tanks, then there's nothing that needs anti-freeze. In theory, if there's a little bit of liquid in a holding tank and it freezes, nothing will happen of any consequence.)
