Macerator pump and 3/4" high quality hose of your desired length. After years of screwing with the "stinky slinky" I would NEVER go back to dealing with that mess. The macerator is great for so many reasons. I mainly got it so I could dump slightly uphill at home and it works great. No more waiting in line on Sunday at the campground, no more worrying about the kids having to "go" on the way home, use your RV at home without worrying about filling the tanks after dumping/cleaning. Then, the dumping just so much cleaner and easier.
