House Battery

I am looking for a battery for my fifth wheel. I guess it is called a "house battery". For the purpose of running my 12V system in the event power fails or for not being connected to a post. My primary question is what battery group do you have, and my other question is what brand of battery do you have. I will have a single 12V deep cycle battery. One store recommended a group 24 and another tore recommended a group 31 battery.

    A bigger battery group 31, or 27, likely better choice, than 24, depending on length of time not connected. If just a short term power disruption, a 24 will serve you without issue. I like the Interstate brand, but most brands will do the job, if fresh to start with, and properly maintained.

    Your existing battery should list the group number, or you might even see the brand and model. We've had good luck buying at batteries plus, and Interstate also stand behind their batteries.
