Do we have to winterize if we use our RV during the winter?

While there are certainly ways around it, I'd advise winterizing everything at risk- multiple times if called for. It's just not that much effort and if you are wrong, the expense/aggravation can be huge.

Perhaps adding some thermometers to check 1st thing each morning could give you a better idea how cold those critical spots are actually getting overnight.

x2. Sometimes temperatures dip without much warning; I would winterize it and then it is not a worry. It doesn't take much effort/time/expense to do it.

For me the answer is always yes if there is any question. I have had frozen lines once and I am sure that drives my decisions. Not a fun time. Im sure that it will get cooler no matter where you live and as was mentioned it has more to do with how long rather then how cold. I am set up so I can winterize in about 5 minutes. Then when I dewinterize I save the antifreeze from the lines to use in the drains next time. By doing that I can winterize with only 1 gal of antifreeze. For me that is not worth the chance that it may freeze up.

Not sure about the Wildwood, but my Forester has all the water lines and fresh water tank above the floor, so if you have power available, use an electric heater as mentioned above.

Two different ways to go... if you are living {camping - traveling} in the rig then flushing toilets and running hot water certainly could not hurt and would be easy to do. If you are not and the coach is not immediately available {as in your driveway vs a distant storage facility} then these methods probably would not be all that doable often enough to effect much protection.

Once I have drained the fresh water from the rig the only thing that goes down any drains or the toilet is the pink RV anti freeze. When we are ready to travel again I just refill the fresh water tank and turn on the pump and we are good top go - with no need to flush the antifreeze as it will just be pushed from the traps into the black/gray tanks.

As always... Opinions and YMMV

I'm seeing similar temps here in central Arizona {at 5,000'} and the short answer is "Yes".
An occasional dip into the mid to high twenties is not likely to damage but... if it drops into the 20's and stays there for more than a few hours or so things will begin to freeze, and not in a good way.

I haven't had the need to blow out the lines and refill them with antifreeze but I do drain all of the water from the coach {and then drive it around for about 5 miles with the drains open and that chases most of the water from the lines down and out} and fill the traps {sinks and shower} with a cup or two and put about a quart in the black and gray tanks.

Our class C resides in the driveway and has AC power 24/7 so anytime the temps are headed south I can just run a small electric heater set to around 50 - 60 degrees. Opening drawers and cabinet doors help circulate the warmer air. Also the rig has tank heaters and I will turn them on anytime the temps are going to stay below 30 for any length of time.

We usually use our coach throughout the year but this is our first winter up at 5,000' so I will adjust the above as needed. good luck.

If you get into the 50's during the day and are able to open it up, do so at the height of the day. Let that cold air out and the warm in.

Close it back up once the temps start to dip. The fresh air won't hurt either.

No, not if you can get it above freezing in the daytime. I put an electric heater in my 5th wheel that will keep the inside just above freezing temperature.

Better to be safe than sorry. Winterizing doesn’t take that long to do or reverse. You’ll need to sanitize regardless.
