We are new to the RV world. We have a 1976 Holiday Rambler 3000 and no idea, except by trial and error, of how things work. Of course we purchased this (temp. home) used and there wasn't any manuals to help out. Hope you don't mind the questions. How do we maintain the vent in the bathroom? We finally got the tanks to drain (thanks scooter) and now we keep dealing with the horrible smell, especially when the wind blows (outside, not inside :laugh: ) Any help would be greatly appreciated!!!
