This is my first winter owning a TT. I do plan to fully winterize it with antifreeze, but do I need to run a heater in it too? It’ll be stored outside and I live in Ohio where it can get pretty cold. I just wasn’t sure if the cold temps would do any damage.
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.
