Larger suction pipe to pump - better?
All inside tubes, inlets on the pump, and suction tube from fresh tank are 1/2". 3GPM pump, 40 PSI on the push side, self-priming up to 10ft (I think). Now, imagine fresh tank 6ft away, sitting on...

If you have a loss of pressure, elevate the aux. storage tank. The small diaphragm pumps used in most RV's do not have a big pump head lift.
I didn't notice a loss of pressure with 1/2 tube on aux tank. Little ugly noise-maker is pushing same sub-par flow (compared to average shore home) with same disgusting noise as it was with the built-in RV tank :).
The aux tank is sitting on the ground, its bottom is ~1ft lower than the trailer tank, but it's taller, so half the time the water level is at least same high as it would be in RV tank.
