Often not. The wiring via the trailer plug and trailer wiring is small enough that there is a significant voltage drop from the alternator to the trailer. No matter how much current you have available, you can’t make it flow to the battery if you can’t get a voltage to it higher than the current battery voltage.
This is the reason people use DC-DC converters and large gauge wiring to the trailer.John & Kathy

Do you check the lights after you turn the battery disconnect switch back on? You may need to actually check the voltage with a VOM and ascertain exactly what the battery charge is. Those lights may not be all that accurate. Just a thought.

Something is wrong with the battery, if you are totally disconnecting it. They do self discharge. Heat speeds it up. But even in Texas/Arizona in the summer you should get several months before much of a charge is needed. In cooler weather at least 6 months. I've has some here in Minn. go over a year, and still be at 80% charge - but our really cold winters help with getting that long of a period.
