New batteries

[wyo700]

I am going to need some new batteries this year. Last season was our first season with my son so we ran the heater at night. 95% of the time we will be boondock camping. I have a generator built in my toy hauler so I will be able to charge them during the day if needed at times. I have two 12 volt interstate RV batteries right now and they are almost dead in the morning to the point then gen has a tough time starting. After reading and talking with other camper owners I was thinking I would go with two 6 volt deep cycle batteries. Any thoughts or recommendations?

If you had room for (4) 6v that would be better.

I have the 4CT's but you can go bigger. These are the best AGM batteries on the market IMHO...

We run a pair of Trojan T105 6v batteries and have never had a problem.We boondock in weather down as low as 25 degrees, so the heater runs quite a bit. I just make sure to run the generator enough to keep the batteries topped of in the evening.

Thanks for the replies. A local battery store has the Trojan 6v batteries. I have heard great things about them. Seems everywhere I read says go 6v.

Remember that not all 6V's are the same output. Take a look at the Lifeline link I posted. Lost of AH options to choose from based on your needs. The real hot setup would be six 2V's putting out 900 AH! If only I had the space.... and money....

They are a different size from the 12V so check dimensions and available space.
