When we clean an RV, we give a "Tank Health" grade, based on the initial flow, odor, cleaning issues (slug), mold... Oliver Travel Trailers owners have done an outstanding job maintaining their investment, after all Oliver's are built to last a lifetime. We also teach how to rinse out your Gray Tank. We have never had 4 different people in a rally to receive an A in at least one of their tanks. Super job and you should be proud. When you see them, ask them their secret.
