The fear of one 6 volt dying and having an unworking electrical system is rather obvious.
But the likelyhood of a 12v marine battery failing unexpectedly is likely twice that that of a GC battery.
Trojan makes group24/27 and 31 sizes and they are rated at half the cycles of the slightly larger T-1275.
Any distributor will gladly sell you a marine battery, its better for their bottom line, now, and when the marine battery needs to be replaced that much sooner.
Its like if oil companies were able to make and sell cars that only got half the MPG and needed their oil changed every 1500 miles.
