More often than not, I dry camp. There are times I dry camp simply due to my not having made reservations and a campground is full. One of my favorite campgrounds is dry camping only, but does have two free dump stations. On the typical big week ends, it can easily be an hour wait in line.
I can say, my Macerator will work anywhere my Stinky Slinky will. My Stinky Slinky will not work where the Macerator will.
As for waiting in lines, I prefer not to wait in any line if there is a reasonable way to avoid it.
