1. There is no holding tank under the trailer. The toilet is the holding tank.
2. Two adults and two kids will most likely fill the tank, with limited usage after 3 days.
3. If you have a site with sewer, use toilet, then when full, dump and recharge.
4. I would recommend RV Paper only. Make a good habit to start with.
5. By dumping the toilet into the drain pipe, you will be dumping a small portion of the content. Less than 1/2.
