Converter problem?

2017 Rpod 180 about 11 months old. 3 weeks before warranty expires. I carefully monitor the batteries (2) with a permanent voltmeter and 90 percent of the time it reads 13.6 volt the absorption rate from what I read. Today after a long drive hooked up 30 amp power at a campground and everything good with air conditioner and appliances. However the volts are reading 12.5 volts on meter and Indepemdant voltmeter taken from distribution panel. I presume just battery power. Checked CBs recycled everything obviously getting 30 amps because Air is working. Seems to me a converter gone bad. I have read about problems with these. I have enough battery power for brakes to get home which is good. Any recommendations for an easy replacement. Does it sound like a bad converter. Any suggestions what to try.

One small correction: The battery is needed to supply power to the brakes if the hitch fails and the trailer becomes separated from the TV. When the pin is pulled by the safety cable, the battery powers the brakes to stop the trailer. That is one reason the cable should be slightly shorter than the length of the chains is so that it will pull the pin and activate the brakes, even if the umbilical should become disconnected.

The stock converter is 55A. I would not go with a lower rating.
