RV sitting for two to three weeks in 10 degree weather

Our family is going to be in the mountains in NM for a month or so, but not staying in the RV and will be staying in my in-laws house for tow to three weeks. possibly four. So do I still need to winterize? I can make sure its all emptied and drained. The issue is I'm from central Texas and it rarely ever freezes here, so I am very worried about cold weather and the effect it will have on our RV. I would hate for the first stop on our 2 year journey to be a disaster. Thanks for the help and if there is more info that you need let me know.
  • The weakest link in winterizing is the toilet water valve. Just blowing it out may not be enough. Best to use 100% non diluted antifreeze in all pipes, valves and drains. And yes, 10 degrees for 4 weeks poses an extreme risk to any water left in the RV. JMO

    PS: Do not forget to drain the hot water tank and any water filters.
  • No question about water freezing in 10F degree weather. You need more that just the above answers. Lots of good information on the internet to read or watch...youtube.
  • If your tanks are empty you only need to put in a quart or less in each tank. This is in case a small amount of water is left in the tanks, it settles against the dump valves if it is level and this will keep it from freezing and damaging the valves.

    You also need to fill the P traps with antifreeze, maybe a pint in each one.

    Enjoy the stay.

    Best to plan on winterizing, your unit is new to you and unless you know how it will hold up in those temps you should take every precaution. We live in NM and unless there is a major storm going through daytime temps usually rise above freezing most winter days. I have always just blown out my water lines adding a bit of antifreeze to sinks, toilet, and shower.

    Works for us, but I know our rig's capabilities very well, no issues over last 20 years, plus we are always ready at a moment's notice to head south to AZ or TX for a quick respite from winter if we feel the urge. Good luck, hope your journey for the next couple of years in your new Class C goes well and is everything you imagined it would be.


    we will be in the sandia mountains, but it sounds like its going to be a bad idea since this is my first time in an RV. when you say put anti freeze in the tanks you mean fill them up?

  • Two to three weeks below freezing anywhere could damage water lines if you don't winterize.

    I,d winterize it. and take all the food out. if just blowing out the lines? don,t forget the water pump strainer bowl and low point drains . put some rv antifreeze in the waste water an poo tanks so no water will freeze at the exit valves.


    yeah that is what I was afraid of, ok thank you, I really don't want to take it up there and have it sit, it would be different and less risk if we were staying in the RF right?
