1997 National RV Dolphin

We have a 1997 Dolphin and are looking for an owners manual... I know this is an impossible task. At very least, could anyone link us to a picture or diagram of the battery compartment to show how all the batteries should be hooked up?

We also need to know where all of the fuses are in it as we are having some issues.

My husband is active duty and we are trying to sell it since we don't know where the next step of his career will take us and we need to get these issues resolved soon!

Thanks for any help!
