Winterizing your camper is essential for keeping it safe from the elements. There are several ways to prepare your camper for the cold weather. How should you go about it?

Winterizing your camper involves cleaning out the interior, adding insulation, and protecting against water damage. If you don’t take care of these things, you could face problems down the road.

What Is Winterizing A Camper?

The term “winterizing” refers to preparing a camper for the cold months ahead. It includes cleaning out the inside of the camper, adding insulation, and making sure that the windows and doors are sealed shut.

If you do not winterize your camper before the first snowfall, you run the risk of having trouble with the heater or furnace in the spring when temperatures begin to rise. You also run the risk of having water damage if the rain seeps through cracks in the walls and roof.

It is important to note that winterizing does not include installing an air conditioner. This is because most campers already have one installed. The only thing that needs to be done is to make sure that the unit works properly.

Why Should I Winterize My Camper?

You should winterize your camper for two reasons: safety and comfort.


One reason why you need to winterize your camper is so that you can keep it safe during the colder months. When there is no heat running, you will want to ensure that there are no drafts coming into the camper.

Drafts are caused by gaps between the door frame and the door itself. These gaps allow moisture to enter the camper. Moisture will cause mold growth which can lead to health issues for you and your family.

Another way that moisture enters the camper is through leaks around the windows and vents. Water can get trapped under the window seals and then leak into the camper. If this happens, you may find yourself dealing with mold and mildew.


Another reason why you should winterize your camper is so that you can enjoy the comforts of home while camping. Many people like to use their camper as a second home. They want to feel at home while they are away from home.

How To Winterize A Camper (1)

When you winterize your camper, you give yourself the opportunity to enjoy all of the comforts of home without worrying about how much money you spent on heating and cooling your camper.

How Do I Winterize My Camper?

There are several ways to winterize your camper. The easiest way is to clean out the inside of the camper. This means removing all the items inside, such as furniture, appliances, and other belongings. Especially perishables. Then, you can add insulation to prevent heat loss. Finally, you can seal off cracks and crevices to prevent water damage.

If you have a camper that has been sitting in storage for some time, there may be mold growing on the walls or ceiling. You should remove this before you start any work on the camper.

Mold spores are very small and will find their way into every crack and crevice. If they get in there, they can grow and cause health problems.

You also need to make sure that the camper is dry. Moisture can cause wood to rot, so if you see any dampness, you should fix it right away.

Insulating Your Camper

There are many different types of insulation available. Here are two options:

  1. Fiberglass Insulation – This is an excellent choice because it is lightweight, easy to install, and inexpensive. It comes in sheets that are cut to fit specific areas. You simply lay them over the area you want to insulate.
  2. Styrofoam Insulation – This type of insulation is less expensive than fiberglass insulation. It is lightweight and easy to handle. However, it does not provide much thermal protection.

Insulating your camper helps keep it warm during the colder months. But what happens when the temperature drops below freezing?

Protecting Against Water Damage

Water damage is one of the most common causes of property damage. When temperatures drop, moisture begins to freeze. As ice builds up, it expands. This expansion damages the structure of the building. In addition, the ice makes it hard to breathe.

The best way to protect against cold weather damage and water damage is to cover the windows and doors with plastic sheeting. Make sure that the plastic is tight-fitting and covers the entire window and door.

You can also use anti-freezing agents like Mr. Freeze in the camper’s water tank during cleaning (not to be consumed).

Sealing Cracks and Crevices

Finally, you need to seal off any cracks and crevices. This includes the seams of the roof and sides of the camper. If these seams are left open, they can let air in and cause condensation. Condensation can lead to mold and mildew. To avoid this problem, you should caulk the seams.

These tips will help you winterize your camper. Remember to check the manual for your camper as there will be a guide to winterizing it there too, to ensure that you do everything correctly. Also, remember to inspect your camper regularly to make sure that you don’t miss anything, like mold growth.

Final Thoughts…

Winterizing your camper is very important, and hopefully, this guide will help you do so in the safest and most efficient way. Don’t be put off by the term winterizing. It may sound fancy but once you break down what you have to do, it’s not too hard.

When winterizing your camper, always remember to follow the manufacturer’s instructions. Also, remember to clean out the camper van first! This will let you know what exactly you need to work on as you go through your camper and clean it.

More importantly, though, perhaps the most important advice of all, do not leave anything perishable in the camper over winter!

The last thing you want is to return to your camper van in Spring and have it smelling of months old nacho dip that you forgot to throw out. All because you thought it was nacho problem.
