Winterize or not before a trip?

We will start our trip when temperatures are freezing where we live but we are arriving at our destination 2 days later where it won't be freezing.

Do I need to winterize the RV and then de-winterize it when we arrive at our destination? Hard to do at a campground. Are there alternatives? Perhaps partially putting some antifreeze in tanks?

Appreciate any advice that can help us.

Do you have the option to blow the lines out instead of running AF through them? It'll all depend on how long the rig is subject to the below temps. If it's a quick trip like you're saying, I probably wouldn't worry about it. But if it's gonna sit anywhere for a period of time, then yeah. I wouldn't do anything to the tanks.

how cold how long.. generally it has to be below freezing for at least 12 hours... i doubt you need to... rule of thumb is every degree below zero you have that many hours before it freezes up.. so if it is 24 you have 24 hours ...

Blow the lines out, and donít worry about the antifreeze. Occasionally, Iíll set the furnace 50į when going down the road to keep it from getting to deep freeze when itís really cold.

Drain the system and leave the taps open. Unless you are expecting a hard cold (unlikely at this time of year), that should be fine. A couple of degrees below freezing outside, the lines inside your trailer will generally be comfortably above freezing and should be just fine.

You should also be okay with a little bit of water in the tanks, but I would try to have them as empty as possible. If your underbelly is not wrapped, they might get colder than the inside but they have lots of room for a small amount of water to expand when freezing.

You can also try heating the inside of your trailer occasionally during the trip if things are getting very cold. Run your furnace for 10-15 minutes every couple of hours to keep things warm.

Another thought (a trick I use at the cottage with an unheated crawlspace) - get a remote thermometer and place it inside a cabinet against a water pipe in an area you think will get coldest. It will tell you just how cold your lines are getting. I use this so I don't have to turn on the supplemental heat to stop the pipes from freezing. It can get VERY cold outside before an enclosed space gets cold enough to freeze.

Your 2-day trip can become a 3-plus day trip in the event of a breakdown or bad weather. Much easier to de-winterize than winterize while en-route.

I depart (mid November) winterized during my 3-day (minimum) trip from Michigan to Texas every winter. Once I'm into Missouri/Arkansas I will consider de-winterizing prior to reaching my Texas destination.

I carry a 6-gallon plastic container of travel water for use of the toilet/sink, and a spare gallon of antifreeze.

Don't know when you are going but we will winterize soon so any trip in the winter involves de winterizing. We do this at a full service campground with sewer hookups.
As Rustic points out travel winterized is easy.
