OK to let Soiree Toilet Freeze?

I am replacing an old guzzler toilet with the Toto Soiree (mostly as a result of my research here)

Its a vacation ski/lake cabin that I use on weekends, but do not keep it heated when I'm not there in winter. Its in NH so it gets -20 at times. I drain all the plumbing lines and pour RV anti freeze in the traps and the toilet tank and bowl enough to make sure it gets all the way into the trap.

My question is about the flushing mechanism. Does any water get trapped anywhere within the plastic parts? its a 1.28g Soiree that I ordered.

(Terry, I'm the guy that called last week trying to order from you to NH.)
I still think its lame that they don't let you do that.

Thanks.

If you drain the tank by lifting the flapper, that will be enough for that.
Whatever gets past the flapper, winds up in the bowl.

Putting a little antifreeze the bowl would be good though.

I wish Toto would let me drop ship too.
It would be nice if they extended the same options to me as they do to others.

Thanks!

Thanks again Terry.
