yep, I don't know why everybody assumed they were good.

Since you no longer dry camp it should work just fine
The big advantage to the pair of 6V=GC-2 is capacity (220 AH give or take and half usable) this compares to one 12 at
Group 24 75 ah
Groups 27/29 just under/over 100 AH
Group 31 about 130 ah And only about 1/4th usable.

So that's the only major difference.

go get a wal mart deep cycle marine battery biggest that will fit. been using them for years no problem.mine are four years old last month.

If you aren't going to do any dry camping, I wouldn't bother getting 2 batteries.

A single 12v battery should be enough.

IMHO A sane choice.

Choose a battery source that would make warranty service easier

Monaramblee,

Any 12 volt battery will work. I'd be tempted to get a reconditioned AGM from your local interstate store (or the like).

That way there would be zero maintenance.

The 6 volt batteries are shot.

No issues. It will work fine. If you don't camp without hook ups then battery capacity is irrelevant. But, I would keep using the 6v batteries if they still work.

Replace 6 volt batteries still giving good service? Why?

No issues but I recommend a G27 as a minimum. Are the GC2 about shot?
