After 35 + years of RV'ing, IMHO a macerator is way more work than they are worth. One big exception might be if you have to go a long ways or uphill to the dump pipe. They are so slow that you leave a lot of "stuff" in the bottom of the tank unless you take the time to flush it several times. Further, if you dry camp and use the public tank dump on a Sunday afternoon, you will have a line up of very unhappy folks who just want to get home and not wait for you to pump stuff out. And finally, I have never had to perform any maintenance on my 3 " dump hose while a macerator will eventually plug up or seize up no matter how careful you are.
