Well, I managed to a get a little bit accomplished the past couple of days. Installed the 12VDC systems, tested the lighting (of course then removed it).
Can't say it is "any good", I just got it this past Friday as well. Group 27, rated at 115 amp hours, so we shall see. Based on my readings, research, and advice from this board, the group 27 should fit the bill. And in the event it turns out to be a dog, it didn't break the bank buying it.
