Where to cut sealed underbelly?

[Decidion]

I need to know where I can cut into the sealed underbelly of my SV-210 so I can install a Tornado blackwater tank rinser. Anyone done this and can give me approximate location?

Thanks

The best way to find out is to remove a section of the screws attaching the underbelly and pull it down a bit and look. The black tank on ours is located directly under the toilet and runs crosswise of the RV.

Hopefully someone with an SV-210 can give you exact directions.

Are you sure it's sealed? The ones that I have seen have all been attached via self tapping screws or some other fasteners so you can remove it to work on items.

Maybe someone else here will know.

Well, it is "sealed" in the sense that it is bolted to the underside of the frame and then they took grey expanding foam and ran it all around the edge. I guess I'll just have to cut away a small section and take a peek...

Yeah I would take off the section rather than cut through it.
