UPG 250 amp hour agm batteries
I just finished up my residential refer install with inverter. I have two 75 amp hour batteries that will suffice for now. But this worked so great and I had so much fun with it, I started searching ...

There is little information to prove that AGM batteries will last any longer than FLA batteries in a very dynamic situation like an RV, where current draws are high relative to the capacities involved. Most of the anecdotal information I've read points to the FLA, larger plate batteries, like GC2 or larger deep cycle batteries garnering the longevity crown.

To be fair, running a fridge is not exactly a dynamic situation re comparing AGM to FLA. It is simply another low Amp draw that accumulates AHs over a long period. This is exactly the usage that gives a deep cycle FLA a decided advantage.
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.
