Storing in climate controlled garage

Do you need to turn on AC periodically in the winter to keep the seals lubricated?
Also, does anybody keep their black water tank full with a bottle of a Unique digest it In it (after thorough cleaning beforehand of course)

We empty our tanks and rinse thoroughly, then put some antifreeze down the toilet and into the gray tanks enough to get some on the outlet gate valves.  No other additive.  We store indoors and do not have access for 6 months.  On the window A/C - if you had one stored at your home, would you plug it in during February just to run it?  Same A/C.
