I am going to be buying a camping toilet soon because evidently my kids can't go for more than 12 hours without having a bowel movement and sometimes its more like 6 hours! Anyway, what's a good one to get and where? I want it to be enclosed and free standing, easy to setup and require minimal effort on my part to dispose of the waste. I will probably use it for both rural camping and campground camping since they have a fear of unclean toilets which, depending on the campground, I really can't blame them. Thanks!
