we bought a water meter that fits a garden hose..works great when filling the black tank to let it sit for a week or two before we head out again..we fill it with about 30 gallons after each trip and let it sit til the next trip....keeps the tank pretty clean...surprised how much still was in there when we did this process the first couple of times..but now runs pretty clean...worth the 24 dollar investment in my opinion...
