I have never owned an AGM battery, but the new trailer I am getting will have 2 of them. I replaced the converter/charger in my previous RV with a PD4655V, and am thinking of installing the same i...

The AGMs are rugged and this charger will do ok. AGMs always need less voltage than flooded cells for proper charging, they have inherently lower internal impedance, so you may want to put in a larger charger as off grid as even a small AGM can take a lot more than 45 AMPs easily without overheating and why run your generator longer than needed if your solar cells don't give enough on a given day.
AGMs do not "always need less voltage than flooded" and some do have charging amps limits. Mine do. These 100AH ones want 14.8ish (same as Trojan flooded) and 27% charging rate.
