Hi,
I doubt that an rv of that age had a "smart" converter. So far as I am aware only 'state of the art' solar controllers have battery voltage sense wires. In other words, your converter can, if left plugged in 24/7 overcharge and destroy the battery bank.

It did say that whenever the AC/DC power convertor is plugged into 120v, the coach batteries would charge automatically. It also cautioned that if another charging source was used, (meaning an external charger I presume), to make sure the batteries did not overcharge. I would gather from that, this means the shore-power unit has a sensor, to prevent overcharging.
