I had some spare macerator pumps and parts lying around from my previous RVs, so I put together a portable unit that attaches to my RV dump value. Attached a 3/4" garden hose to the output and built a adapter for the other end that screws into the 2-1/2" clean-out on the side of my house.
Thought I'd need to tap into the 4" sewer and install a dump there, but this setup just works. I'm not trying to pump up-hill or anything and my 3/4" hose is 50' in length.
One trick I learned is to fill the sinks with water in the house where the clean-out is that I use. This keeps the macerator pumping action from siphoning the water out of the P-trap in the house which can result in sewer smells in the house during and after use.
