I don't believe its so much a bad connection. The slide hydraulic pump draws significant power from the battery. The wire run from the pump to the battery is very short. The path of least resistance. By exercising the slide you are drawing more power than the converter can make up to recharge the battery.

The LP gas detector does behave just like a low DC voltage alarm. I experienced this in my last camper also. They must use a comparator op-amp. When the two voltages being compared (sensor and a reference voltage) the alarm trips. By having low DC power being supplied to the LP gas detector. This comparator circuit voltage threshold is met causing the alarm to sound.

I briefly explained this after the Tornado warning and power failure episode at the NE rally last year in Lake George NY.
