I am afraid you might have to explain that one.
1158 posts from you and you don't know what a sewer donut is for? Sorry, I thought you were joking around. Please accept my apology.
Now I will be serious with the topic.. The sewer donut goes into the sewer pipe at the campground. Some campgrounds don't have threaded connections and even if they do some require the donut to "make an airtight seal". The op was asking what he needed and he may or may not want to use one. So far, I have not but I have only been TT camping for about 8 months and I know what a sewer donut is for. I hope this helps...
