No, it’s not the aqua hot.
It is rather loud, sound like it is a variable speed motor, you can hear speed change, sometimes it goes off for 30 seconds or so then restarts. I noticed I am also getting a red led light on the rear of the voltage regulator while this is happening.
If I throw battery disconnect to.off sound stops, and I can turn back on, and no sound.
It’s not the hydraulic fans, sound is in engine compartment, not from under coach.
The valid gizmos for slides are located forward about mid coach, it’s not them.
Could it be something to do with the exhaust regen on the cat engine??
