2006 jayco granite ridge where is water tank and pump

In our old Escapade, the Manual says the fresh tank is under a cabinet or sofa. That would put it on the floor. It's actually under the floor, transversely across the coach, pretty much over the axle. I'd expect a GrannyRidge to be laid out a little more nicely, but our pump is on the kitchen floor under the oven. Yep, in otherwise useful space, along with a patchwork of valves for tank fill and winterization.

Look at the upper left hand side of the utility compartment for the pump (behind the aluminum panel) Not sure about the water tank, but my guess is right above the tank low point drain and probably above the axle.
