I just got a 1981 Toyota Dolphin today and I wanted to know if the lights only work on shore power? I think I found the break box under the sink area? If it does only work on shore power how could I setup my own battery bank to be off-grid for longer periods of time? How do you start the refrigerator and the heater using gas? I would ask the previous owner but he wanted it gone that day b/c he was moving and sold it pennies on the dollar but signed the title over and he had to finish packing so I'm stuck here brand new to the whole r.v. idea and clueless like a hog in a corn farm lol so please help I want to hit the ground running so I can take my family camping soon lol
