Here in the midwest a cold snap can roll through in the middle of the night and if not winterized properly, components of your camper can come susceptible to freezing and breaking. Being proactive and getting your camper treated with Rv approved antifreeze before winter weather comes is always recommended. After those cold winter months it is time to dewinterize and get the antifreeze out of the fresh water system and begin the process of prepping your camper for the spring and summer months of travel and adventure. We will always recommend using antifreeze to help insure that your fresh water system is treated properly to prevent damage to your camper.
