Like ScottG said, DW tabs need HOT water to be effective. It is also a fairly corrosive detergent and I would be worried what it would do to the rubber seals on the dump valves. A healthy squirt of Dawn dish detergent before you hit the highway with about 10 gallons of water in the tanks will do a decent job of getting rid of any residual gunk clinging to the sides.
