At the end of the RVing season and before you put your trailer or motorhome into storage for the winter, you should winterize your RV. For those who might be doing this for the first time, we tell you everything you need to know about winterizing.

Here’s what it means to winterize your RV, who should winterize their RV (do you really need to?), when this process needs to be done, and how to do it.

What is Winterizing?

Winterizing your RV simply means preparing the internal systems to withstand below-freezing temperatures. This process involves removing water from:

  • Water lines
  • Holding tanks (grey and black)
  • The water heater
  • And any other water systems your RV might have

Even if there is a little bit of water left in the system, the freezing temperatures can cause the system to freeze, expand, and damage your RV. Remember that water expands when it freezes.

Methods for winterizing your camper

There are two common ways to winterize your RV. One method involves adding RV anti-freeze and the other involves blowing out the lines with an air compressor. Regardless of the method, the end goal is the same: to get the water out of your RV’s water lines.

When Should You Winterize Your RV?

There are three scenarios for when you should winterize your camper:

  1. Temperatures are going below freezing
  2. You’re traveling through an area with a cold climate
  3. When you put your RV in storage

When temperatures go below freezing

If the area temperature is going to dip below freezing for more than 24 hours, you should winterize your RV to prevent damage to the plumbing. Alternatively, you can pack up and drive somewhere warmer.

When you’re traveling through colder regions

Even if you’re headed south to warmer temperatures, keep an eye on the local temperatures. You might be tempted to stay in summer mode, but a sudden cold snap can wreck your plumbing and cost you time and money.

When you’re putting your RV in storage

Lastly, regardless of where you live and where your RV is going to be stored, you should winterize your camper.

Do You Have to Winterize Your RV?

Unless you live in your rig all year round in a location that never experiences freezing temperatures, then yes.

How to Winterize Your Camper

Now that we’ve established that basically everyone needs to winterize their camper at some point, let’s get into how. Below is a step-by-step guide to completing the winterizing basics on your own!
