Do you run a heater in your stored RV over winter? September 22, 2024 at 2:33 pm #41849 IA_CamperParticipant Joined: Jan 2024 Posts: 109 Likes: 113LikeUp1::Nope. As long as you winterize it properly you are good to go. I live in Iowa and store stored mine outside for many years with no issues. A heater, imo, is a waste of money and a potential fire hazard.
