There should be two hose bib fittings on the top of the tank that come through the floor under the dinette bench inside the frame rails. One is for the sink drain input, the second is for the vent. A hose attaches to the vent fitting loops up then exits back through the floor on the outside the frame rail. There should be a hose bib fitting under the floor on the tank for the shower drain that may need to caped if you don't have a shower drain. The large drainpipe is usually sealed in the tank with RTV/ silicone. (I use black.) Most importantly, cut a wood block (2x6) and attach it to the underside floor and form fit it to the drainpipe and secure the pipe to your block with pipe strapping. You want a good solid support for your drainpipe.

The heavy strapping, I got from a lumberyard, it was used to band landscaping timbers. I bolted the straps the floor drop metal and rear floor angle iron support.
