Thanks to all for the suggestions. As it turned out,the first answer from furpod was right, as usual.Apparently the batteries were not fully charged from sitting on the shelves. The batteries were manufactured in July, 2016. After being hooked up to shore power for a day, they have been flawless since. I got them from Sam's Club at a cost of $112 each. They are Energizer CG2 and rated at 122ah each.

Batteries usually come charged ready to go so here's the questions,
1  Are all the the cables tight to the battery terminals?( and the plastic caps removed. iv'e seen it)
2  2 6 volt batteries are wired different than 2 12 volt batteries, are they wired correctly?
3 Is the ground tight to a clean metal contact, No paint?
 I second the refer on gas suggestion, but there is no reason if all is correct they should die so soon.

Also, with GC2's, you get TRUE deep cycle batteries, which are less likely to be damaged when deeply discharged.. (below 50% capacity)

The answer is capacity, cost, and effectiveness. A single 12V GP24 battery like supplied with your camper has a capacity of 85AH. Two 6V GC2 batteries provide 220AH. It would take three GP24s or two GP27/30s in parallel to approximate this capacity. Due to the huge number of golf carts in the world the GC2s can be less costly.  And due to physics, battery cells work better in series instead of parallel. The cells in two GC2s are all in series. Paralleling multiple 12V batteries puts the cell groups in parallel which is not as good. See the following excerpt from the Trojan battery catalog:

Which is best depends on the kind of camping you do.  If you mostly hook up to shore power, a single 12V battery is all you need.  If you boondock a lot, you need as much storage capacity as possible.  2 group 27 12s will give you about 100 usable amp hour.  2 6s will give you about the same, but since they are true deep cycle batteries, they can be recharged many more times than the two 12s and can deliver higher voltage for longer time than the 12s.  They tolerate deep discharge better than the 12s

"RV industry" and "QC" have no discernible association.

In fact, it almost seems like they're mutually exclusive.

Also check where the battery cable ground attachment to the frame is. Mine had a coat of paint between ground cable and the frame. Only way and return voltage was getting back to the battery was via a few threads on the bolt. FR really needs to get a good qc program going.

enjoy the fresh air
