I finish all the preparations, before the toilet is installed in the van. The toilet has a mechanism, that allows it to be on a sliding drawer, while being connected to the gray water tank, which is located under the van. I use a PVC connector at the bottom of the slider and an identical connector on the floor of the van; a flexible hose in between, allows for the sliding motion. In this video a 1/2″ PVC pipe is installed inside the toilet and where the pipe goes through the floor on its way to the waste tank.
