Leaving RV anti-freeze in the grey / black tanks for a week?

Thinking of just de-winterizing our camper at the end of our drive this season and I don't want to just dump the anti-freeze from the lines in the street, and I don't feel like trying to hoist our honey-bucket into the house to run it down the toilet.

Is there any issue (other than weight and sloshing) to leaving the water / rv anti-freeze combo in our grey and black tanks for a week, until we go camping next weekend and swing through the dump station?  There'll also probably be a few gallons of sanitizing solution (bleach + water) in the tanks as well.

  • RV antifreeze is "generally recognized as safe" propylene glycol.  If it was safe enough to sit in your pipes and water tank over the winter, it is certainly ok for a couple of weeks in the gray/black tanks.
