Wag Bags or Double Doodie Bags - these have many names and are all the same - a double bag system containing a special powder that solidifies liquids and deodorizes whatever goes into the bag. You can buy these in most camping stores and Walmart sells them in the camping department. They cost about $11 for six bags and one bag holds a lot - change the bag at least once per day, however. These bags are made to "go" directly in - most fit into the toilet seat/bucket or frame potties and also will fit into a standard RV toilet. The bag once double sealed is legal to dispose of in any trash or garbage receptacle. We use these when we travel in the winter and have winterized our plumbing. Use public facilities when you can and use these when you must be inside the RV.
