Is Six volt even an option? Seems like all I have seen are 12v systems....thinking your right Ice

some say its better,,
"two 12-volt 24 group batteries wired in parallel provide 140 to 170 AH. Parallel wiring increases amp hours but not voltage."
"pairs of 6-volt batteries need to be wired in series to produce the required 12-volts and they will provide 180 to 220 AH. Series wiring increases voltage but not amp hours."

six volt is an option, you have to wire them in series to produce 12volts...

:yeah:
Wiring 4 six volt batteries (2 batteries wired in series together and then wired to each other in parallel) is a good option for trailers. Of course it depend on how much you use your trailer to be worth it although the cost isn't much more. If you use it more in winter and have high loads often (ie furnace, all lights on ect..) then the 6 volt option would work better and batteries will last longer on a charge. If its mostly summer use and once or twice in cold weather then the 2 12v batteries should be just fine and wouldn't be worth the conversion :twocents:

Thanks for the help guys. I think I will go with the two 12 volt batteries as I dint do a lot of winter camping. This site rocks!better to have a generator also,if ya don't already Tim,

This site rocks!A pair of group 31 Trojan AGM batteries will keep you powered up for a week, if your careful on what you leave on. Mine have lasted me 2 weeks in sub-freezing temperatures.
6 volts wired in series are the way to go, clearly. But a pair of 12v AGM's are the next best choice.

Wow! Trojan batteries are not cheap. I think Les Schwab might be in my price range.those will be fine,I have never had a problem

One of the reasons I went with the 12's versus 6 is that I was concerned about someone else wanting them. As stated the 12's are much cheaper, the solar panel I have was $100 and I didn't mount it permanently for snow/freezing rain.
Please tell us more 'bout yer Solar Panel. Where'd ya get it, how big is it, ratings?
thx

FYI there are only like 3 battery manufactures... Different brand are marketing... Costco normally has a good deal on batteries... Same kind as everyone else... And the heavier the battery the better. :twocents:
Spot on. Costco is the place to go for batteries. I've bought a few for my diesel pickup and tractor for less than you'd pay at Walmart and probably half what Les Schwab or a dealer will charge you.

6 Volt is by far the best, but takes up a little more room, and can be pricey.
You can buy Optima batteries at Costco, too.

The 6V batteries are much more robust than 12V.
I went to two 6s a couple years back in my fifth wheel. Not going back to 12s
