He doesn't have a Thor MH.
The radio has two power supplies:
House for operation
Chassis for memory

That explains a few things.

OIC. So, when the spring thaw comes, you can sit in one place and listen to music while you're waiting for the tow truck.

Except he says his radio is not powered by the house battery.
So maybe no music while we're waiting for the tow truck.

Yes, and the concerns with drained batteries and need to add auxiliary chargers would tend to support the theorem. I was just stating how I check periodically to confirm 0% parasitic drains and you questioned that 0%. I was just clarifying what I experience. I have spent a lot of hours just testing my batteries and what is typical on daily basis. When I thought I had an issue with just the LED on the ANT/ Cable switch I would NOT accept as Normal. I got it resolved. I also am reluctant to add any aftermarket products that will draw on batteries if the my House Switch is OFF.

Actually I have a switch on the Dash Panel beneath the Radio. When it is forward the Radio is off the Chassis and I need the key to turned to accessory, or engine running for radio to come on. However, if I flip the switch it goes to the House Batteries Additionally, there is another switch in outside cabinet next to outside TV that I can switch the two outside speakers to play TV sound, or the Radio from inside the coach. I can also bluetooth music from my phone outside to the radio inside to the speakers outside while waiting for tow truck.

Drove myself nuts trying to find parasitic drains on the house and chassis batteries. Found the 100% cure for parasitic loads -- put a knife switch on the house batteries and another one on the chassis battery. When you put the RV in winter storage, open both knife switches. There is absolutely no power drain from parasitic loads when both sets of batteries are physically disconnected by opening the knife switches.

Added a cutoff switch under the hood of our old class C to fix a drained chassis battery problem. It did take a week in storage to drain, but was a pain and did not want to spend hours when a cutoff switch wound suffice.

Yes sir, that was one of the 1st things I installed was disconnect switch on Chassis. See upper right. My SOB House Battery ON/OFF switch works to perfection as is; so no need to do anything for it.
