on a 12V forum. Anyway, my Sundance came with just 1 group 27 12V battery. This is not an acceptable arrangement for me since 95% of my camping is boondocking. Usually two to three nights at a time. Need two batteries. I was ready to buy a couple of 6V golf cart batteries until I realized I don't know how to charge 6V batteries. I camp out in the woods, so it is not plugged in while I'm camping. It sits in a storage lot when not in use, so it's not plugged in there either. Typical drive time from house to setup is less that 2 hours, so I know the batteries won't charge in that amount of time. With my 12V batteries I would put them on my work bench between trips and hook my trickle charger/maintainer up and they were ready to go whenever I was. I've heard and read that 6V type chargers are quite expensive. Just wondering if anyone could enlighten me or educate me further about how to get along with 6V batteries. Maybe just another 12V and call it good? I do already understand the benefits of paired 6V, so really don't need to go too deep into that conversation.
