SaniCon and Cold Weather Camping

I have plenty of experience in cold weather camping, but on my other motorhome.   I could put a light bulb in the wet bay and take other precautions.  I never experienced any problems.  My concern now is the SaniCon system and my PC.  I understand that the freshwater tank is safe under the bed and the holding tanks are heated.  My question is:  The sanicon system is relatively exposed to cold temps.  On my way to south Texas for the winter I could possibly experience some sub freezing temps, more especially at night (getting a late start).  Will the system be OK?  Is there anything I need to do?   Put some pink stuff in the grey water tank and do a quick flush?  I appreciate any comments.  TIA

Barry, I think you are right on-track.  I suggest first draining the gravity pipe completely by removing the 3" cap.  If nothing comes out, then my suggestion is mute.  Then do as you are thinking.  That will make for the highest concentration of anti-freeze in the Sanicon system.
