Hello all, own a living lite 11.0S 2016 Truck camper and suddenly developed battery charge issues during a recent cross country trip. Battery will only charge via the shoreline and will not hold a charge. Questions, where is the battery located? I am sure I need to service it. Ie distilled water. But I cannot locate it. Yup, I feel real stupid, but, still smiling, love the camper. Ford logo model, on a one tonne ford.
