Thanks Ianerd and Metaphor - The reason I'm looking for a unit that doesn't need "installing" like a regular macerator is the cost. That is why the Sewer Solution appeals to me. I can do this myself without much investment. I have seen the video a couple of times and it really looks great. I can't see too much of a problem with getting water at the dump station for the garden hose.....our local park has two available. I am mainly interested in seeing some actual hook-ups that show it connected to my specific 2004 Roadtrek. My husband always struggled with the dumping and I helped him, so I know it's because the RT is so low and has to pump over the curb. He always had to "milk" it until every last drop was out of the hose or it wouldn't go back into the tube so the cotter pin could be put back in place. For me, with a knee replacement, it is a problem. Thank you both very much for your input.
