If there's a third battery I'd like to know where it's hiding.

I'm waiting to hear who made it and why did it last ten years.  Then again it sounds more like a third battery wired in parallel to the other two for either the generator or the main engine and located accordingly.  In the Rockwood, to get us safely through the night, I hid four 6V GC batteries under the bed along with a charger/power supply in addition to the two group 27s in the slide out tray.

My current task, four weeks in and I'm down to the last wire nut to remove:

May be very difficult and expensive to legally dispose of at end of life, or the guys in the black suits may pick up whether you like it or not. Amazing they have been operating for two months. A part number would be appreciated. I want some

The mystery battery is probably technically dead, but being in parallel has a surface charge after the two main batteries are disconnected. He mentions that the fans were turning slower.

Maybe the mouse is getting tired or the bearings on his wheel are binding up? :))

Do you still have 12v at night with the batteries disconnected? My money is on a solar panel you didn't know you have

Although you still have a mystery, thanks for the update.

When you said you disconnected both batteries, did you mean both house and engine/chassis batteries? Your dash radio is powered by the chassis/engine battery if like ours. Another possibility is that your isolator is bad or not wired correctly. Ours was when we bought it.

Power and heat source

The 238PuO2 radioisotope thermoelectric generator of the Curiosity rover
The isotope plutonium-238 has a half-life of 87.74 years.[122] It emits a large amount of thermal energy with low levels of both gamma rays/photons and spontaneous neutron rays/particles.[123] Being an alpha emitter, it combines high energy radiation with low penetration and thereby requires minimal shielding. A sheet of paper can be used to shield against the alpha particles emitted by plutonium-238. One kilogram of the isotope can generate about 570 watts of heat.[6][123]

These characteristics make it well-suited for electrical power generation for devices that must function without direct maintenance for timescales approximating a human lifetime. It is therefore used in radioisotope thermoelectric generators and radioisotope heater units such as those in the Cassini,[124] Voyager, Galileo and New Horizons[125] space probes, and the Curiosity [126] and Perseverance (Mars 2020) Mars rovers. Also one 88 Grand Villa 36'  was outfitted but we have lost track of its location or current status.
The twin Voyager spacecraft were launched in 1977, each containing a 500 watt plutonium power source. Over 30 years later, each source is still producing about 300 watts which allows limited operation of each spacecraft.[127] An earlier version of the same technology powered five Apollo Lunar Surface Experiment Packages, starting with Apollo 12 in 1969.[37]

Plutonium-238 has also been used successfully to power artificial heart pacemakers, to reduce the risk of repeated surgery.[128][129] It has been largely replaced by lithium-based primary cells, but as of 2003 there were somewhere between 50 and 100 plutonium-powered pacemakers still implanted and functioning in living patients in the United States.[130] By the end of 2007, the number of plutonium-powered pacemakers was reported to be down to just nine.[131] Plutonium-238 was studied as a way to provide supplemental heat to scuba diving.[132] Plutonium-238 mixed with beryllium is used to generate neutrons for research purposes.[37]

Disconnect the ground at the batteries .
 I have the same year and  the start battery is driver side rear box , closest to the engine.

Yours then is way different to mine, my rear box has my power cord and oil. Two batteries under the stairs, left is chassis and right is coach.

Right
Mine shows something about 3 rd battery option . Was 2 start batts , one under stairs , second in rear bin.
Now is 1 start and 2 house .

And mine shows third battery option was to up the coach capability, so one battery in back for the motor and two underneath the steps for the coach.
