Re: fix the camper roof ~ question.
Go with the eternabond, It's easy to use(Like a roll of tape) and lets FOREVER. Look to the camper forums for your answers. Make sure you remove the old silicone and clean the surface thoroughly, this stuff will work forever unlike silicone which has to be stripped and resealed roughly every two years. My new Northern Light uses it to seal all roof openings.
Its expensive but works.
