Do I require a vent on a RV toilet

Cheryl AEm


We currently have a conventional household toilet in our RV. It is directly piped to a black water tank below the trailer floor. I would like to put it directly into the sewer, as we have no intention of moving the trailer. My question is do I need to vent the ABS pipe coming directly from the toilet to the sewer? I will cap off the black water tank. Can I use a small vent pipe unerneath the trailer? Any help would be greatly appreciated. The owner of the campground said it was ok for us to do it
