More Tips For Winterizing Your Trailer

We store our folding tent trailer outside with no problems and take these precautions as part if the winterizing trailer routine.

Lubricate Metal Parts of Your Trailer Over the Winter

I do this for my pop up trailer, a Fleetwood Sun Valley 2007. I buy a can of silicone lubricant. When the trailer is open and I am putting antifreeze in the water lines we spray the metal rails at four corners of the trailer, as well as the metal stabilizing jacks.
The silicone is waterproof and protects the metal over the winter.

Protect Protect Hitch and Power Connections

A neighbor showed me this one. Take large pail- preferable tall- put over the hitch connections on the trailer. It will cover them nicely and protect from weather and snow.

Make Sure not Mice and Other Critter Get In Your Trailer Over the Winter

First get rid of any food or crumbs that might be left in the trailer. Check under mattress and cushions.
I am not sure if this has any merits. but we also put scented dryer sheets everywhere. Our dealer told us this trick- I am nit sure if or how ti works but he said they don;t like the smell. I tuck heavily scented sheets all over nooks and crannies of the trailer for the winter.

Preparing Trailer for Winter: Checklist

-RV Anti Freeze in water lines. Don’t forget to pour a bit down the drain as well- and turn on ANY shower taps as well.
This process is explained step-by- step in Winterize Your Pop-Up Trailer

-Cover tires if outside- this protects the rubber from sun.

Remove/store battery and use a trickle charge to keep it “healthy” especially if you are using a deep cycle or RV battery.

-If you have a portable potty- take inside, this will also freeze.

-Make sure no food. shampoos, cleaners, etc left in trailer- will freeze and make a big mess. Food will attract critters.


Winterizing Pop-Up Trailer – Storing RV/Deep Cycle Battery over Winter months

I would remove the battery and bring into garage or inside. Set up with a trickle cell charger ( cost about 20-30 dollars, can buy pretty much anywhere, Walmart, Hardware stores, etc.)

You can also use a low amperage ( cheap) solar cell panel for your battery- as a TRICKLE charge only. Don’t expect this to “charge your battery for you..


Winterizing Pop-Up Trailer and RV- How to Winterize Your Trailer

When should you winterize your trailer? I do it when I know I am done camping for the season. If you camp late into fall keep an eye out for freezing temperatures. If a glass of water would freeze outside then its time!

These are general Winterizing instructions- If you are unsure about what you are doing then I do recommend the winterizing ofyour trailer be done by an experienced RV Technician.

Drain all the water from the system by opening the drains on your fresh water tank, water heater, and any other valves in your water lines. Don;t worry about a small amount in your fresh water holding tank.

Open all faucets. When all water has drained from the system, turn your water pump on to expel any water remaining in the fresh water line.

Check that holding tanks are completely drained.

Next, close all taps, drains, etc., making sure that the city-water check valve is secure or plug the service port.

To put NON TOXIC RV ANTIFREEZE through the hot lines as well as the cold, you must by-pass the water heater. Some have a by-pass already on the trailer. If you don;t- consider installing one to save time and effort each year, If you have no bypass you must detach the hot and cold lines from the back of your water heater and join them together.

Next, we pour NON TOXIC RV ANTIFREEZE by removing the inlet hose on your pump and inserting it in the antifreeze container. If your inlet hose is not long enough, use another length of hose.

Doune checl that all the tap are closed. Next turn on the water pump go to the furthest tap and open it until you see the coloured antifreeze come through. Do the same with the hot tap, then go around your trailer and open each tap. Remember to do toilet as well.
Shut off the pump and release the pressure by opening any tap.

Go outside your trailer and remove the screen at the city water depress the inner stem, stand back and wait for all the antifreeze to drain out.

Last step is to pour about a cup of the anti freeze down each drain.

Open the by-pass on the water heater or remove the temporary by-pass.
