Actually a BSM controlled Lithium solution is more drop-in friendly than AGM as its circuitry could handle pretty much any input. AGM can be a drop-in for most automotive uses however in an RV the float mode from the typical stock converters is usually set too high. AGM use in an RV is best by selecting the AGM battery type switches or at least adjusting the float mode down if possible. Swap out the charger if necessary to one that is AGM selectable/adjustable. I did AGM as a drop-in replacement for the coach supply some years back and basically fried them in one season. An expensive lesson!
