This may be one of my shortest posts in history! But playing on the internet and looking at some articles around the proper management of the gray/black water drain pipe I found a really great bit of terminology.
The most common RV drain hose is a spring wire which is coiled and wrapped with plastic. It is basically very similar to a plastic covered slinky. They are anywhere from 5-20 feet in length and condense down to perhaps a space as small as 2 feet long. They normally store in the bumper of the RV or camper but I've since found that the bumpers are really good at destroying the drain hose. I'll post a solution in the near future for that.
But here is your RV term of the day which defines the RV drain hose : Stinky Slinky!
