How to winterize trailer?

Hey guys this is my first trailer and I'm just wondering what I should do to winterize it. It's stored at an RV storage outdoors and up here in Canada gets cold in the winter about -40 Celsius, any help would be appreciated thanks

The owners manual will provide you the best information. You should be able to look up the RV manual on line. You can get manuals for the equipment (pumps, battery, etc) on line as well.

These will give you the details on your RV.

If you search for winterizing on the firms you should find other members lists/ recommendations.

If you still have questions or need addition information post them here again. Proper winterizing of your RV should be a detailed list for your installed equipment and configuration.

P.S. If you choose to use RV antifreeze make sure it non-toxic RV/Boat/Pool propylene glycol without menthol or ethanol in the mix. These could lead to problems for the plastic holding tanks and could quickly corrode the anode rod in the water heater.

I don't recommend filling the water heater with antifreeze, leave it empty.

You should have instructions with your rig on how to remove ALL the water for Winter. If not, then it may be worthwhile to have someone do it with you for the first time. Do not forget the freezable stuff inside.

It might seem complicated but it is simple to do. You do not indicate what type of rig you have.

Empty the hot water tank and turn on the bypass.
Empty the fresh water tank. Do not put the pink stuff in the water tank. The little bit of water in there will not hurt anything.
Put the pink stuff into all your water lines using the water pump.

If you have a washer or ice maker you have to winterize them too.

remove the anode, let water drain, leave anode out, get a new one for next

year even if the old one looks good.

There is an interesting thread here about winterizing using compressed air. There is also a good one here if you want to use the pink stuff.

All good advice about the water system, but winterizing should include more things like- plugging any access points for small animals/insects, cedar blocks/ant traps/moth balls, prop open fridge, tires off the ground, spray/lube screw jacks, antennas, steps, any small rust spots on frame, pull & store indoors main battery, make sure everything is sealed up tight, pull batteries out of everything- remotes, smoke detectors, etc.,

Lots of You Tube videos on the subject. Just start looking around. Lots of opinions on which method is best, compressed air to blow out the water or RV antifreeze. I prefer the antifreeze, since you are asking, you can get it at Walmart or there camping outlets for 3/4 dollars a gallon and without knowing what you have you can probably get by with about 3 gallons. I think that the compressed air method will leave some water still in the lines, just like when you blow water through a straw, no mater how hard you blow you can still get a drop after it sits for a while. Just don't forget to drain the fresh water tank and get as much out of the black and gray water tanks as possible, put a little RV antifreeze in each of them since you want to protect the gate valves, your commode and all the "P" traps, don't forget the shower faucets either. Open the low point drains on the hot and cold side. Drain the water heater and put a plug back in after you drain to keep insects out of it, it's also a good time to check the anode rod if you have a suburban WH and get a replacement if needed. Be sure to put your water heater in bypass when you winterize. Again, lots of You Tubes on the subject.

And as Smithers says, lots of other things to do to winterize besides the water system. Mice like to take up a home for the winter also, as well as other critters.

Stop back in the spring and we will discuss dewinterizing.

How to winterize trailer?

I would highly recommend wintering in Texas. You won't have to do anything to your rig besides getting it here and you can extend your camping season. LoL!
