Steps For RV Winterization: Pink Stuff and Other Tips

For weekend and part-time RVers, fall is an awesome time to take your RV out and enjoy those cool, crisp nights and brilliant fall colors. However, with winter around the corner and the end of the camping season near, RV winterization will soon be a top priority. 

Properly winterizing your RV is the key to placing it in its winter slumber so it will be ready, willing, and able to hit the road once those first signs of spring arrive in a few short months.

While your RV is in storage, it will be susceptible to extreme freezing temperatures during the winter months. There have been enough past winters to prove to us that almost no one here in the US can escape.

Unless you plan on heating your rig continuously, your water lines could freeze and possibly split open. This could mean an indoor flood come springtime, or sooner.

To protect your water lines, there are two methods for winterizing: blowing them out with compressed air or filling them with RV antifreeze.  

Both methods require using some antifreeze. I recommend using Splash, which is specifically designed as an RV / Marine Antifreeze. One difference between the two methods is that the blowout method requires far less antifreeze. It will only be used in drains and holding tanks, rather than filling all of your water lines.

The Blow Out Method

This method is usually reserved for those who are located in slightly warmer climates or climates that only see a few nights of temperatures below 32 degrees each winter.  

STEPS TO WINTERIZE USING BLOW OUT METHOD

The following are general steps to get you through this process. You will need an RV blowout adapter, a standard oil-less air compressor, and one or two gallons of RV antifreeze.

The Antifreeze Method

For those who live further north or who live in mountainous areas that see snow and sub-freezing temperatures throughout the winter months, RV antifreeze is the method to use.

WHAT IS RV ANTIFREEZE

RV antifreeze is made of ethanol, propylene glycol, or a mixture of both. It raises the freezing temperature to prevent your plumbing lines from freezing. The following are general steps on how to winterize your RV with antifreeze.

Depending on how big your RV is, it may take up to 6 gallons of antifreeze to fill all the plumbing lines, fixtures, and holding tanks for protection.

STEPS TO WINTERIZE USING ANTIFREEZE METHOD

The following steps will guide you through a winterization process using the RV antifreeze method:

This article wouldn’t be complete without a few more RV winterization tips. Another important step that should be part of your winterization process is to care for the interior of the RV.

Be sure to remove any food products from inside the RV, along with any other items that you may not want to attract any furry four-legged friends or insects.

Also, remove any items like bathroom or beauty products that you do not want to freeze. We also take this opportunity to wash all of our bedding, wipe down all cabinets, and clean the entire bathroom, including the shower stall.

A clean RV will be much easier to de-winterize and prepare for another camping trip next season, especially on short notice. You will be glad you put in a little effort up front, trust me!

Of course now that you made sure the interior is ready for winter storage, do not ignore the exterior. A proper winterization process needs to ensure the seals, awning, windows, and roof are clean, secure, and protected. That exterior shell is your RV’s first line of defense against the winter elements.

I like to start with by completely washing our RV. That includes the roof, sides, front cap, and rear wall. Remove any dirt to reveal seal breaches or other potential issues.

Repair any seals that are cracked or showing signs of degrading and apply a good coat of wax to the front cap, sidewalls, and rear wall. Condition all slide seals, and apply lubricant to all moving slide and jack parts.

Trust me, there is nothing worse than starting off the camping season with an uncooperative (or leaking) slide!

Now that your RV is fully ready for the “ravages of winter”, storing it will be the final step.

Covered storage is best at protecting your RV from the winter elements. If you do not have the option or resources to build or pay for covered storage, a fabric cover can be almost as good and give similar protection.

We have a cover specifically made for a fifth wheel that we cover ours with. It provides protection from the elements but allows us to keep the RV at home in case we want to take a quick trip or a long winter vacation to some warmer climates.

No matter your RV type or your location, winterization is a process that all RV owners need to go through. Taking the time to accomplish the task properly will absolutely pay off in the end.  It’s worth taking these simple steps to ensure your motorhome, travel trailer, fifth wheel, or camper is properly prepared for winter storage.

Doing so will not only help you avoid costly repairs down the road, it will give you peace of mind that your rig will be ready for new adventures come spring!

Happy winterizing, and we hope to see you on the road!
