A few thoughts
I would cut the FW tank out of the loop unless you are worried about it freezing. A line from the last point of the hot water side to a winterizing valve between the tank and pump will do. Since I don't have the diagram for the plumbing in your rig, I'll explain it with mine.
As the FW is pumped to the back of the trailer, it hits the kitchen sink, then the tub, bath sink, toilet and finally the HWH. From the HWH the process is reversed and it ends at the kitchen sink. So I would run a line from the hot side in the kitchen to the valve between FW tank and pump creating a closed loop that will require less pumping and much less propane to keep the lines warmer.
