You want a "Marine" battery as it can handle deep cycling better than a standard automobile battery.
However, the actual size of battery will depend on how much room you currently have for a battery. You need to figure out the group size of your current battery. Perhaps your battery box is actually large enough for a bigger battery than what you currently have in the box? If so you might install a larger battery.
For example, my Class C RV originally had a somewhat small house battery installed under the hood. I relocated the connection to install two Group 29 Marine batteries (from Walmart)in battery boxes in a cargo bay under the RV.
