Strange gurgling/pumping/motor noises in my motorhome

[ichudov]

I have a Monaco Windsor 40 PST motorhome.

When the engine is NOT running, and nothing else like water pump is supposedly running, I hear strange gurgling or motor noises.

I recorded this with my cell phone and posted to youtube:

Do not listen to the sound that sounds like crumpled paper. Listen for deep sounds like gurgling or motor running.

I know that it is NOT affected by the "whole house" switch next to the exit door.

Any ideas what it may be, it is driving me crazy.

It seems to happen more towards the front of the RV.

Can it possibly be your Aqua Hot water heater/Furnace system? They have circulation motors that run coolant thru the floor heat radiators AND thru the engine block if you have that switch turned on. The floor radiators also have small blower motors to blow the hot air out. Doug

When I go to the address it says it is private so I don't have access.
