What size battery do I need for the cab of a "C" class RV?

ANSWER Greetings Don thanks for submitting your question on our Ask An RV Question Page.

When you talk about the type of battery you should use for the cab of your Class C RV, I have to assume you mean the battery that powers the 12 volt accessories in your RV. My recommendation is that you use at least two 6 volt deep cycle batteries to power the house portion of your RV.

We have all kinds of information on our website about why you want to use at least two 6 volt deep cycle batteries instead of one 12 volt battery to power the house portion of your RV. Take a moment to review the answers I gave to the following questions to get all the information you need on RV battery systems:
