I believe you are mistaken about that. When winterizing, you should set the valves so that the antifreeze does not go into the fresh water tank. You do NOT want antifreeze in the fresh water tank. It would take forever to get out. The fresh water tank is "winterized" by simply draining it through the low point drain.
You DO want to sanitize the tank and all the lines. So the sanitizing additives, what ever it is, should be put in through the port that fills the tank, and then pumped through the water system.
I agree with everything except not putting anti-freeze in the fresh water tank. A previous trailer of mine did not have a winterizing port so I would pour the antifreeze into the fresh water tank and use the pump to distribute it throughtout the system. I never had a problem flushing it out in the spring when I sanitized the system.
