Turns out the 2 red wires on the old detector were connected to a single purple wire. The black wire on the old unit was connected to a white wire on the camper side. I checked the power to the unit by disconnecting shore power and leaving battery on and the green light stayed on. I then turned the batteries off and plugged in shore power and the green light stayed on. Then turned on battery and shore power and green light stayed on.
I then connected the single red wire on the new CO detector to the purple wire and the black to the white. The new detector stayed on with all of the same on/off scenarios as above.
I guess the purple wire must be a 12 volt feed that the converter system keeps hot by whatever means it determines and keeps the detector functioning as long as there is any power available to the converter.
I will probably get a battery powered unit as others mentioned as a fail safe. You only die once and I want to delay that as long as possible. Thanks to all who responded.
