Hello, I am new to this, but about a year ago a dear hunting friend past away. I inherited his late 1960's-early 70's Hi Lo. It has been sitting in a field for about 10 years. needless to say, I am thinking about re-vamping it to make it usable again. First off, the electrical cord seems cut off, but I am not even sure it is the electrical cord. There is a cut off/broken exterior heavy coiled wire in the front, by the propane tanks. That wire looks like a HEAVY duty coiled phone cord. Does anyone know if this is the electrical cord? I need to be able to raise the camper up. Second question: can the camper be raised manually?
