Extending stay/ Blackwater?

The wag bag system worked for us till we got the new black water tank installed. Used the potty in the bathroom by placing the bags in it securing mnemonic said bags with the lower seat ring. We still carry a supply of them to extend stays and where there are no dump stations to dump blue boy that we also take along. We have no gray tank in our old Shadow Cruiser so blue tank is used mostly for get water. We dig hole and bury everything well away from streams or lakes when remote camping. Hubby had no problem with outdoor pee calls but me.....not so much. Bags online and or Cabela's and Bass Pro. Used them a lot when we tent camped.
