How to Prepare Your Trailer for Winter: A Step-by-Step Guide

As the weather cools down and camping season comes to a close, it's time to think about preparing your trailer for winter. Proper winterization can save you from headaches come spring, protecting your trailer from freezing temperatures, moisture, and pests. Here’s a guide to keep your trailer in top shape through the cold months.

1. Drain and Winterize the Plumbing System

One of the most important steps in prepping your trailer for winter is winterizing the plumbing system. This prevents water from freezing in the pipes and causing them to burst.

• Drain the water tanks: Start by draining the freshwater, hot water, greywater, and blackwater tanks as well as opening the low-point drains (if equipped). Open one tap to allow for faster draining. Be sure to flush the blackwater tank thoroughly to avoid any residue.
• Blow out the water lines: (Optional) Use an air compressor to blow out any remaining water in the pipes. Need a blow-out plug? Pick one up at Village RV for $11.95 + tax!
• Add RV antifreeze: Close low-point drains and taps. Locate the back of the water heater and switch the bypass valves to winterize. Disconnect the line coming from the freshwater tank to the pump and attach a separate line with pump fitting (available from the Village RV parts department) and place the opposite end into a jug of RV antifreeze. Turn on the pump and starting with the farthest from the pump, open faucets one side at a time until the water changes to pure antifreeze. Pour approximately 1 ½ cups of antifreeze into each drain to purge the water and protect the trap. Flush the toilet until pure antifreeze appears. Outside kitchens with plumbing, outside showers, black tank flush line, ice maker/water dispenser in the fridge, and washing machines must be winterized as well. You may need two or more jugs of antifreeze to complete the process.
• Turn off the pump and open one tap slightly to relieve pressure in the lines and close the tap. Go to the exterior pressure water (city/campground) connection on your RV and remove the small screen. Gently push on the plunger to allow the water in the line to be purged and replaced with antifreeze. This may need to be repeated to purge all water and get adequate antifreeze in the line. Leave the grey/black water valves open for air to circulate in the holding tanks. It’s important to use RV-grade antifreeze which is designed for freshwater systems. Automotive antifreeze contains toxins harmful to humans and should never be used. Pick up your antifreeze at Village RV for $6.95/g + tax.

2. Clean and Inspect the Exterior

Inspecting your trailer’s exterior ensures it’s sealed against harsh winter weather, preventing leaks and moisture damage.

• Wash the exterior: Clean your trailer thoroughly to remove dirt, debris, and bugs. This helps prevent corrosion and keeps your trailer looking good. Inquire about our exterior wash service! Call/text us at 306-525-5666.
• Inspect all seals and caulking: Check around windows, doors, and roof seams for cracks or gaps in the seals. Reseal or re-caulk areas as needed to prevent moisture from seeping in.

3. Protect the Tires

Your trailer’s tires can suffer during winter if not properly cared for.

• Inflate the tires: Inflate the tires to the manufacturer’s recommended pressure. Cold weather can cause tire pressure to drop, so check them periodically.
• Cover the tires: Tire covers protect the rubber from UV rays and harsh winter elements, extending the life of your tires. Stop by Village RV to pick up tire covers starting at $49.95 + tax!

4. Take Care of the Battery

Cold weather can drain your RV battery faster than usual, so proper care is essential.

• Disconnect the battery: If you won’t be using your trailer during the winter, disconnect the battery to prevent it from draining.
• Store it in a warm place: Keep the battery in a cool but non-freezing location. Fully charge the battery before storing it and check its charge periodically over the winter.

5. Cover and Protect the Trailer

A quality cover is one of the best investments you can make to protect your trailer from winter weather.

• Invest in a good RV cover: Look for a cover that’s breathable, waterproof, and UV resistant. A high-quality cover protects your trailer from snow, rain, and sun exposure while allowing moisture to escape. Contact our parts department today to order your ADCO RV cover—on sale now, save up to $120!
• Cover vents and openings: Use vent covers and insect screens to block any openings that could let in moisture, pests, or cold air.

6. Interior Preparation

It’s not just the exterior that needs attention. Prepping the inside of your trailer is equally important.

• Clean thoroughly: Wipe down all surfaces, vacuum, and remove any food or perishables that could attract pests.
• Leave drawers and cabinets open: This helps air circulate and prevents moisture buildup that can lead to mold and mildew.
• Add mouse deterrent: Place slow-release rodent repellent near possible entry points for mice, such as under the sink, in outside compartments, and around slideouts. We recommend Rodents Away Odor-Free sachets, available for $44.95 + tax. Contact our parts department at 306-525-5666 for more information.
• Turn off propane: Ensure your propane tanks are turned off and properly stored.

Properly winterizing your trailer not only protects your investment but also ensures that, come spring, it’s ready to hit the open road without issues. By following these steps, you can avoid common winter-related problems and keep your trailer in top condition for many camping seasons to come.
