For all intents and purposes, I've completed the winterization, but
I have
a couple of lingering questions:

SFWIW:

Gave up on potable water anti-freeze after first year and did the
following:

1) Disconnect hose from potable water tank supply at pressure pump
inlet and allow tank to drain into bilge.

2) Disconnect hose from discharge side of presure pump as well as
opening all potable water faucets allowing distribution hoses to drain
into bilge.

3) Disconnect hoses from inlet and outlet of hot water tank and allow
to drain into bilge.

4) Pump bilge.

5) Using a 5 gallon bucket and a 3 ft length of radiator hose, mix a
50-50 anti-freeze water solution in bucket.

6) Attach one end of 3 ft hose to engine cooling water inlet and the
opposite end in bucket of anti-freeze solution.

7) Start engine, run until anti-freeze runs out of exhaust discharge
thru hull, then stop engine.

8) Remove batteries and take home.

That's it.

Worked well in Northern Ohio winters for over 10 years.

BTW, engine was raw water cooled.

YMMV
