In my 24.1 I have it mounted right in the sewer compartment.
To me it seemed the best place in terms of convenience .
I also have a FloJet electric pump to empty my tanks and have placed my power hook up for the Flo Jet in that compartment as well.
I did look at the option of putting the Tornado hook up in the black tank compartment but found the sewer compartment easier and more convenient.
I can get you a picture if you like.
