If your TV is fully charged the alternator will not be putting out enough voltage to charge the trailer battery. The output of the alternator is usually determined by the voltage level at the TV dash. Wire size and distance to the trailer further reduce the voltage. A #10 wire from the TV battery to the trailer plug will significantly reduce voltage drop. Turing on your headlights may also up the system voltage (watch the voltmeter on the dash to see if this has an effect). Are you leaving the TV engine running and the trailer plugged in while you lower the landing gear?
