I use a Sears Marine Platinum AGM for my electric trolling motor. For me, the advantages are: 1) easy charging, 2) very slow self discharge, 3) sealed construction.

1) "Easy charging". I have (built, actually) a constant current, constant voltage power supply. I just set the current maximum (short circuit the cables) to 15 amps, and the maximum voltage (open circuit the cables) to the AGM recommended voltage of 14.5v. Then I connect the battery. Next morning, disconnect the battery. Done.

2) "Slow self discharge". If I recall from the specifications, AGM batteries self-discharge is .5% per month. Essentially negligible. I don't need to keep a float charger going over the winter. Toss the battery in a corner and forget it.

3) "Sealed construction". Speaking of tossing batteries...! No filler caps, use the battery on its side if desired. No leaks, no corrosion.

3 years of service powering my trolling motor and no complaints. After an 8 hour day of fishing I typically measure 12.5v so there is plenty of spare capacity.

I think about running two in parallel in my future '21, but then the reality of paying $700 for batteries hits. Ouch.

My main reason (initially) for going with the AGM batteries in my cars was that I sometimes forget to check the levels and/or clean the terminals like I should. The battery in my sports car is located under the floor of the trunk -- easy to forget its there. With an AGM that isn't a problem. I still think a quality flooded cell battery like a Trojan will give you slightly better performance in an RV than an AGM will, but the maintenance free aspect of the AGM, and the ability to take more cycles, makes it very attractive.
