I pretty much agree with having both, I haven't found any advantage to having a macerator when staying at campgrounds with dump stations, however, on those occasions when I can't or don't want to stand in line to dump, I like being able to dump at home and that requires a pump. I do feel that a Tornado Rinse system is absolutely great, so much easier and faster than a wand or hose down the toilet.
I have, however, found one campground that does no allow macerator pumps. they wouldn't say why. But they had as many rules as the big campground in Haines, AK.
