What size house batteries for 3010DS

Hello Everyone,

It's time for my house batteries to be replaced they are on their last leg, I have a 2013 Sunseeker 3010DS.

I am looking at 12 Volt AGM Batteries to replace my current ones and the 2 batteries together are 250AH.

My Question is what is the largest Group size battery that I can install into the space provided by Forest River?

Thanks in advance

You have to measure the space then look up the size of the battery you want to use. I have 2 Optima group 31 batterys in my step, but another brand group 31 may not fit.

I used two group 31 AGM Duracell's from Sam's. Fit was perfect and they have performed well.

I was surprised 4 Costco 6 volts fit in my CC Hathaway. 430 amps.

There is no extra space!
