I have a 1965 hi lo 1000. I am new to campers. Does anyone know what type of roof it has. What is the material? Mine is pretty wavy and has a low spot around the vent where it has a small leak. Do I take this roof off and replace? Not sure how to fix this. I may be new to campers but have found I can fix most anything. I have already installed a complete charging 12v converter system and 30amp service.
