Which battery runs what???

We just bought our first RV....a 1996 Tioga Montara. We can't find anything that tells us which battery under the truck hood runs what. There is one on the left side of the engine...and one on the right. Is there any way to know which is which?

    Actually its pretty simple. First look for identificstion. Second remove the ground csble from one and see what does not work. Third, the batyeries will lead to an isolator, so you can check thst.

    Totally guessing.. but they both may be for the engine, connected in parallel. Check the wiring. I always thought coach batteries were in the coach part.. somewhere, like under the steps.
