Well my Odyssey died. Had it on the shore power after we got back. It seemed fine. Unplugged shore power and let it sit. About 2 months ago I came out to get working in the thing again (mainly organize shit) and the battery was dead. Charger brought it back to life. A week later it was dead again. I verified that I had not left anything on in the trailer. Charger would not bring it back again. Bought a charger that supposedly can repair damaged batteries and has an AGM setting. Still nothing. Took it back and got my $$ back because they don't carry it any longer. Bummer. Options are an X2 Power group 31, same damn battery just different color. But its also gonna cost about $75 more. Go cheaper with a non-AGM.. but I don't like the idea of a non-sealed battery bouncing around in the tongue box and if for some reason it gets flipped over.. nasty. Interstate has a dual purpose AGM marine battery I might go with.. but it also more $$.
