I'm just going to throw this out there. After having macerators on my larger boats for many years I was thrilled when I discovered that 5th wheels and MH's don't generally come equipped with them. They tend to get plugged and/or wear out and leave you with full black tanks when you really need to dump.
I am not a big fan of the power washer which are built into most black tanks either. I use a Flush King on the end of my sewer boom. I can back flush each tank separate as many times as I want. Never odor problems and never anything to fail.
