Hello, this is my first time posting. We have a 2015 Forest River Sierra SEF33ORLS 39' 5th Wheel and are fulltimers. Our batteries are not holding a charge and just looking for recommendations on what we should replace them with. Existing are 2 Interstate Extreme Cycle 6 Volt! Thanks for any advice you can offer.
A little research will show that 2 6 volt batteries are better than 2 12 volt batteries. Will be going to two or four 6's on mine soon. Far as brand...Ford - Chevy - Dodge - or ???, lots of opinions out there.
Why not use the same batteries? Interstate sells a good battery.
X2. And you can find Interstate batteries everywhere, even tiny podunk towns. Interstate is all we use, although for our RV we use two 12v SRM 27 Marine/RV deep cycle. But if you already have 6v, might as well stick with it. https://www.interstatebatteries.com/...ies/deep-cycle
