There is a frequent clicking coming from under our Rushmore Springfield.
We are permanently parked so I'm assuming that it is not towing or movement related. It 'sounds' like a relay opening and closing. Furnace, A/C, water pump not running. It has a residential frig running on AC. Anyone have any ideas? Thanks for your input.

Generally audible relays can be heard from a furnace fan coming in and out / or the furnace trying to start
Or a water pump pressure pump clicking as the pump is shutting off with head pressure. Try running your pump by opening a tap. Does the sound go away?
Try shutting off the city water supply ( as you said you were parked) and see if the clicking stops. Try turning off the 12v switch that runs the water pump.
