Keep in mind that you need to be plugged in to shore power in order to use the tank heaters. If not, your house batteries will be drained very quickly.

Yes since the black tank is inside the AI, the only thing exposed to freezing temps is the piping, dump valve, macertor, and the hose. That assumes the interior is maintained above freezing.

Glass half full or half empty to an engineer is the glass is twice as big as it needs to be.

I used mine two winters on trips. Blew out lines with air, flushed toilet & sink drains with about 1/2 gal antifreeze, then put emptied tanks and flushed Mercator and line by emptying tanks and pouring antifreeze in black tank until pink froth came out of Mercator line.

Used toilet and flushed liberally with antifreeze. It was in teens & 20s and I didn't have any issues.

If you work until you have everything you 'WANT' - it will probably be too late to enjoy it.
Live in the Moment and enjoy today.
