The first RV I owned, a 2005 Holiday Rambler Endeaver, came with a macerater and I had zero problems with it in seven years. After watching others with the gravity fed hoses, and using them myself, I will take the macerater any day. Not nearly as susceptible to making a mess, and very compact to store and easy to use. Empty black tank first, then grey, and then flush with clear water and see it run clear. I changed from the gravity hose to a macerater on my 2012 Itasca ellipse which came standard with the hose before we went on our first trip. I keep the hose in case of a problem with the macerater, but based on my prior experience don't expect to have to use it. It cost under 300 bucks and I simply unscrewed the hose and screwed on the macerater motor assembly and ran two 12vdc wires for power which were handy near the motor.
