Hello fellow rv'ers!
Question? Should I keep water in my tanks black, gray, and fresh to keep seals from drying out? If so how much?
If it's like all RVs I've had you'll never get them completely empty so there's always a bit in them.
I usually added a gallon of so with a 1/4 cup of cooking oil or 1/2 gallon of rv anti freeze to keep seals lubricated.
