Exploring the belly of a 2006 3670RL

[EllsworthToohey]

Learning about my 2006 3670RL - everything important that the owners manual does not come close to telling me. In this instance I would like to know where the Fresh water tank is.

I just pulled out the belly panels to expose the Grey, Black and Galley Tanks, but I cannot see where the fresh water tank is. I have only exposed the underbelly from the front back to the axles.

I am guessing that the fresh tank is somewhere toward the rear. Way back almost to the rear bumper, there is a hose with a valve at the end hanging down through the rubber belly pan. Is this to drain the fresh water tank?

I will be dropping the Galley tank to maybe repair a drip drip drip leak around the outlet drain. Just wish to know where the fresh water tank is located. I wish the owners manual told more about how the systems work. For the most part it just tells me that I have this or that system; and its not even exclusive to my model. Its a generalized document for a series of models.

Hoping an owners group will be the key to knowledge.
