This photo shows a view of the fresh water tank location not normally seen - from the front. Note the L shaped utility channel around the base of the fridge cabinet. That channel will be in an outside air temperature region due to the lower fridge vent, so it will be important to make utility holes in adjacent locations to fit the utilities, e.g. 110V wiring, 12V wiring, etc.

There will NOT be any water runs through this area with the possible exception of the galley grey water drain line. It's alternative location will be between the range and fridge in a small but potentially suitable area. The reason for this is because if a future taller fridge is ever needed, the whole cabinet shown below the fridge in the above photo will "go away" and I'll be left with a mere 3/4"-1.5" below the base of the fridge for utility access. Even if using a build design for the larger 1.5" height, that doesn't leave enough space for a proper 1/4" per foot slope on the drain line portion parallel to the camper front wall. So I'll probably avoid that area altogether right from the start for water lines of a gravity feed nature.
In this next photo there are 4 points to make.

1. Note the tank is shifted toward the passenger side from a center line. That should assist the weight distribution of the higher number of heavy appliances on the driver side (fridge, range, water heater). The other side (passenger side) also has its own weight, both of which change through the course of use (grey water tank, propane tanks).
2. The 12V water pump will be mounted on the camper box wall (driver side under the step) and that's where all the fresh water lines will run, which based on my fresh water fill design will be quite minimal and will include: tank drain valve, tank fill valve, winterizing antifreeze pickup and bypass valve, and the pump connections themselves.
3. The galley grey water drain hose, 110V cables, 12V wiring and propane supply line will all be routed over and/or around the fresh water tank between the camper's left and right sides. Some of these need a gravity slope and others just need to be "out of the way".
4. This view shows the modification made to the cabinet wall, between the tank and the great room, and gives a clear view of its change in dimension to accommodate waste can receptacles between it and the tank. As mentioned before, that move greatly enhanced storage availability without taking much floor space. There is still ample foot room for moving about in front of the range.
Here's some better views of the space available to the water pump, fresh water connections and a one or two gallon storage location for RV antifreeze jugs.
