AGM does have the advantage whenever dynamic includes high wattage inverter draws. That is, draws that cause the deep cycle FLAs to sag and precludes desired use of the bank by the RVer.

Each RVer needs to choose the battery type that fits their style.

There's a caveat to this though. FLAs work perfectly for high wattage draws. There's tons of people here that do this all the time. The advantage with AGM's in this situation is if you only have room for TWO batteries but want to repeatedly use the MW or other high draw device with a partially discharged battery (say less than 60% SOC). 4 6V's (FLA's) work just fine for high draws IF you have the room for them. Also, 12V FLA's only have a little less sag than AGM's. It's the 6V's that have the biggest sag but you can simply add more then there's no problem.
