I winterized the trailer 2 days ago, and tonight it is going down to –10c, 14f. We actually thought we may get back out for another weekend, but nope, it’s all over for the season.
My method of winterizing is as follows.
1. Drain the fresh water tank by opening the drain valve on the front of the camper. Close the valve and put 4 gallons of RV antifreeze into the fresh water tank. Open the drain valve again until the pink stuff start to pour out, then close the valve. I made a handy funnel from a water bottle and a chunk of hose for filling the tank as it is quite messy and awkward to try and pour straight into the water inlet.
2. Drain the hot water tank from the outside access panel by removing the plastic drain nut and opening the relief valve. let the water drain out, then replace the nut, but leave the relief valve open. (Don’t worry, if you forget to close it, in the spring water will spew out and remind you the first time you fill the tank).
3. Open up the access door to the water pump and water heater from inside the camper and switch the water lines to bypass the hot water tank. It is closing the top and bottom water line to and from the tank and opening the line that connects the two in the middle.
4. Now turn on the water pump and methodically run the taps until the pink stuff comes out of each. do the hot AND cold taps as they are different pipes, even though they are in the same sink or tub. Run the tap into both sides of you sink so the traps get filled with the pink.Don’t forget about the outside shower.
7. Turn off the propane, furnace, fridge. Close the vents, make sure the hood fan vent is closed, Take out the LCD (LIQUID crystal display) TV and store in a dry warm place (don’t forget the remote and power cord, you may want to use the TV at some point this winter).
10. have a really good look around the camper just to see if anything is out of place, and check the tire pressures. We store all our chairs and other camping gear in the camper, as we don’t have much storage at home for this stuff. I did fill the black and grey tanks about 3/4 full, put some bleach in, then went to the Flying J and dumped one last time. That’s it really, pretty simple. We do place about a dozen Irish spring soap bars around the interior of the camper as it seems to keep the mice out. Traci had already done a deep cleaning of the interior, so it is ready to go when we are next May!
