I just spent 10 days camping at the Oregon Coast Gathering on the southern Oregon coast. Ten Forward has a 30 gallon black water tank. Due to the virus, I didn't want to use the campground bathrooms (showers closed). I left the gray water valve open for six days. Multiple showers and the toilet used almost exclusively. Day 10, open and drain the black water tank, flush hose with gray water. Flush black water again with four gallons of clean water. Stow hose, connections and Sidewinder. So very easy. No extras needed besides one bottle of toilet chemicals (The 100% biodegradable waste holding tank treatment comes in child-resistant bottles and is even safe for septic tanks), And NO plastic bags! I don't get where people think this is difficult or smelly or gross. I've changed a LOT of blow-out baby diapers and at least when draining RV tanks I get to wear gloves.
