Installation TOTO in wall tank/carrier same as Geberit

If there is a thread on this, I could not locate it.
Geberit has a great video for installation of their in-wall carrier/tank. Is installation of TOTO's in-wall tank/carrier similar enough that the Geberit video can serve as a general guide? I know the TOTO has a written installation guide, but just for planning, the Geberit video is really helpful.

They make carriers for 2x4 and 2x6 walls. the tank sits inside the wall, so it seems a little iffy to put this on an outside wall. If you open up your wall, there is a very good chance that you will find plumbing vents there. Those will need to be moved. It's a pretty major change when a carrier like this is added.
If you decide to install on an outside wall, it may make sense to add some thickness to the wall and put foam board behind the carriers tank to prevent freezing.
