second on not using diode for voltage drop reason.
Not normal at all!
Trailer brakes only send out 2 volts, and a max of 6 when full brake is applied. Not enough to run anything in the TV. trailer brakes are completely separate system and olny connected to trailer battery when the emergency pin is pulled. Major issues if the brake is at play. maybe installer puled 12v power from the TV to run to the brake controller and somehow crossed wires, if so then start over from scratch.
More likely your trailer batt is powering up your ignition wiring, instead of your TV battery wiring as is common. This would mean the power to the trailer is coming off an ignition wire (wire that has power only when the key is on) that is connected to the radio, so maybe is on the same circuit,fuse as the radio.
Someone in this case pulled power from the wrong place, but seems like this situation would blow the radio circuit fuse if the trailer battery is low enough to pull a strong flow of amps.
The radio will kill batteries over time. Nuisance to have to unplug all the time. You dont want the TV battery drained from using your camper either.
