Here is what has happened the last time around with the dead chassis battery.
The Axis was in for service Friday. On the ride home the house power switch was in the on position. The Axis was in for a new driver side mirror as the camera stopped working. The radio was switched on so I could see that the new mirror solved the camera issue. It did. When I arrive home and before I turned off the motor I plugged in the the Axis into a 30 amp outlet. I also plugged in a ceramic heater to keep things from freezing.
After a few minutes I shut down the engine. As I prepared to leave and lock up the Axis I noticed the radio was still on. I pushed the button to turn the radio off but it did not go off. I thought that because the radio was being powered from the shore hook up/house batteries I thought nothing of it and locked up the Axis.
This morning I went into the Axis just to check on things and noticed that there was small blue light on the radio flashing. I tried to start the Axis only to find the battery dead. This is the 3rd time this has happened. Each time the Axis has been connected to shore power.
In this case the ceramic heater was still working just fine.
So, I hooked up the chassis battery to a battery charger for 30 minutes and was able to start the Axis engine. With the engine running for a few minutes I noticed that the radio was off.
My question is, is the radio powered from the chassis or house batteries?
My confusion comes from the fact that you have to have the house battery switch on to get the radio to work but turn signal activation brings up the camera view on the radio screen. I was under the impression that the dash controls were chassis battery powered with the exception of the radio. If the turn signal lever can activate the radio screen does this mean that chassis battery power from the turn signal lever links chassis battery power to the radio?
I am trying to narrow down where the drain on the chase battery is coming from. I suspect the radio but am not sure.
Any thoughts or advice would be greatly appreciated.
Thank you for your time, too!

If turn signal activation turns on the radio screen when the switch is in the "store" position, it looks like that part if the radio system is tied to the chassis battery. That did not happen in my first Vegas and it does not happen in my new Axis. The rocker switch must be in the "use" position for the turn signal to activate the radio and cameras. I have always thought that for safety, the cameras should turn on from the turn indicator even if the rocker switch is in the "store" position, but in my Vegas and Axis, they do not.
Your radio is apparently miswired and it is draining the chassis battery. I would also check the condition of the chassis battery. The chassis battery is not a deep cycle battery so unlike the house batteries it will take being discharged down to nothing only a limited number of times before it will no longer hold a charge. It seems likely that every time the coach has been run since it left the factory, the chassis battery has been fully discharged when it is turned off.
