It is important to winterize your RV travel trailer to withstand winter temperatures if you store your RV travel trailer in most of the US or Canada during the winter months. Failure to properly winterize your travel trailer could result in burst pipes and damage to your travel trailer plumbing system. It is important to winterize your travel trailer anytime the outside temperature is predicted to fall below 32°F. Repairs needed on your travel trailer due to freezing are not covered under most limited warranties so you will want to protect your investment by properly winterizing your travel trailer. We also recommend you get someone to assist you when you begin to winterize your travel trailer.
