You can use 2 twelve volts or use 2 six volts. You have to wire them properly but the 6 volts will give you longer service. Go to the Trojan battery website and learn more than you ever wanted to know. Enjoy the new rig!

We had a 25ft Arctic Fox TT before the coach. We had 4 group 27's and one group 24 batteries in parallel. This amount of battery would allow us 5-7 days of winter boondocking without charging. So, I would say that more batteries equal a more useful TT for us.

It all depends on how you plan to use your RV. More battery equals longer boondocking.

Napa are good batteries but consider this...

The GC-2 Six Volt Golf car battery is a True DEEP CYCLE battery, this means it can safely be taken to 50 percent state of charge before serious damage to the battery starts happening.

And even if they are taken lower for a short period of time, they may recover.

Most 12 volt (The GC-12 is an exception, but then it is a Golf Car Battery (GC)) are starting batteries,, or MARINE/deep cycle, These are damaged way more by likely to be damaged, fatally, by a deep discharge, and the cut off is also higher.

I would replace with a pair of GC-2 or if that wont fit a GC-12, Costco, Sam's. or your local Battery Dealer. Mine are DEKA
Home is where I park it!
