You could do it now if it's not temperature dependent by pouring it into the toilet/shower drain and adding water with a hose in the toilet and shower drain. Where would you dump the tanks when you're done?
Best to leave the tank drained as much as possible...no anti-freeze required.
Thanks Dave, I contacted the Digest-It manufacturer and received a reply today stating that it would work fine down to a temp of 32 degrees or lower since the bacteria produced heat as they were working. I think the best thing for me to do though is to wait and use the Digest-It in the spring as I'm getting the camper ready for our first trip of the season. Thanks again everyone for all of the helpful comments.
