I don't know a single thing about draining an RV toilet, but what I do know is that I'll leave it to the professionals! I know when you're out on the road it might be difficult to find one and you'll have to do it yourself. I bet this Dad regrets his decision!
In the video on TMZ, a Dad is trying to drain his RV Toilet into a street drain like he's cousin Eddie from Christmas vacation, and while he is trying to do that... the hose comes loose, spilling tons and tons of dark brown sludge onto the ground and sending the family running and screaming for their lives! You can watch the video below!
