My wife and I bought our first travel trailer about a month 6 weeks ago. We have a Forest River Wildwood 282. We've only been able to go camping once since we bought it. We have not winterized yet. We are planning on going next weekend here in South Carolina. The weather forecast has varied a lot over the last few days but is now showing a 24 degree low on Friday night. We will be running the heat in the camper while we are in it and plan on winterizing at the end of the weekend. Should I be concerned about anything freezing / getting damaged while we are camping? Thank you for your help!
