Taking care of your RV's waste system is an essential aspect of maintenance that you should never overlook. One of the most important things you'll need to do is empty your black tank regularly. A good rule of thumb is to dump your tank every three to five days or once it's two-thirds full. By sticking to this schedule, you'll ensure that your camper van stays free from unpleasant odors that can quickly ruin your outdoor adventure. Plus, you'll avoid any potential backup issues that can cause a major headache.
