You keep saying that your battery monitor shows 100% full, but don't post voltages. I am assuming that you are talking about the idiot lights on the RV wall. That light will show 100% charge anytime the voltage at the battery (note that I did not say OF the battery) is 12.7v or 12.8v, or somewhere in that area. Since the absolute LOWEST voltage your PD will output is 13.2v, that idiot light will ALWAYS show 100% charged while plugged in. It is responding to the PD's voltage, not the battery's voltage. That is a totally meaningless reading.
If you want that idiot light to have at least SOME meaning, unplug the RV from shore power and let it sit for a day for the battery's surface charge to dissipate. Then, and ONLY then, will that idiot light have any POSSIBLE meaning. But, it will still be only a vague indication.
