Thanks for the replies everyone. I will have to find out what converter, charger is and post. I'm sure it is OEM.
I like the idea of 2 GC batteries but was thinking that 2 Group 31 would be about the same. But the GC batteries would not require a new box.
My current wiring, my negative wires both go to ground. So I would just have to take the positive from one and run to the negative of the other. Can I use the same wire? Seems like I can.
I see lots of negative reviews on the 6V at Costco so I will look to see who is the Interstate dealer in my area. My cousin used to own a dealership in Portland but he sold it a few years ago. Too bad, it would be good to have that in now. Is there anything wrong with Batteries Plus?
