Hi Zach, well my 2013 coach still has its original wet cell batteries but we don't do much boondocking.....and I have been using a Progressive Dynamics Intellipower Converter (PD4645 I believe to replace the OEM converter early on). It is a 4 stage converter and works fine for the wet cell batteries......not sure it is AGM compatible though, but it is probably time for me to consider new batteries.....AGM perhaps. Hopefully others who have the PD series converters or some known AGM compatible converters will chime in here.
