If they are difficult to perform the watering, go with AGM!!! Love my two 8D8A AGM batteries. Don't boondock, but when I want to dry camp somewhere for a couple days, I don't have any problems having enough juice to run the furnace, lights, cpap breathing machine and computer. If I did a lot of boondocking, I might consider the 6 volt, but would probably go with the AGMs because of the lack of watering convenience!
