I’m leaving Massachusetts tomorrow for our inaugural trip in our Winnebago Itasca, Sunstar 30T. I was told that filling the freshwater tank is okay if the heat is on to at least 55 degrees. Now that I’ve done this I fear I’ve made a mistake.

Please advise, should I flush the whole system?

Thank you

Drain, yes. Flush not required.

As long as you keep the belly warm and keep some heat going inside as well (open all the cabinets where any water lines might be located) then you will be fine. It doesn't need to be 65, but around 40 is pretty safe. The water tank itself is unlikely to have issues as the warmth of the water will help keep temps more stable in the belly area. IF, IF, you have NO exposed sewer drain pipes or these pipes have no fluid in them then they are OK at any temperature but once you flush you will have to keep all drain pipes exposed to those kinds of temps warm as well. Once you get away from the 17's and into the 35's then you are good to go for most anything you like.

We have relatives in Massachusetts and they are predicted to get to 10 degrees Fahrenheit tonight. I would run an small electric heater on low or medium in my sewer drain pipe area. I would open all cabinets and sink and shower doors as well as leaving the thermostat set on 45 or so. Run the water heater to temp if you have water in your fresh water tank.

You’ll be surprised how warm the basement stays even in cold weather when on the road.

FLHTCI,

I am also in SE MI (like Old Wizard). Our climate is not that different than MA. I know, I am a refugee from the east coast Megeapolis. If you keep the temperature in the coach comfortable, there is no reason to drain the tanks.

Be sure to have enough LP for heat in case you get stopped. but other than that there is little to worry about. Yes, you might like to leave cabinets that contain water lines open.

If you should find an open cramp ground to stop at that might freeze, fill the potable tank and run from that. If you have to get out the potable water hose and are not sure it is going to stay warm, drain it before you stow it. If it gets to freeze, it is a problem.

Unless you run a great deal of water, the black tank will not freeze, but the gray can. That can often be (capriciously) dumped into a storm sewer.

Leave the furnace working and you'll be fine.

I am less adventurous than most of you. I would have it winterized until I met warmer temps. Coming back from a FL trip to MD one year in a previous MH, we hit a nasty storm. 19 degrees. An hour later my water pump in the basement was frozen despite having the heat on.

My Winnebago has a road heater on the lower dash. The engine coolant circulates all the way to my water heater and is fan blown.

I have made two trips to Florida most winters in my Sunseeker Class C from northern NJ since 2013. There have been a couple of times where I have not dewinterized until there (it was single digits when departing - I'd have gotten frostbite on my fingers), but have successfully flushed the tank and piping as well as filled up with fresh water with the NJ weather at home an ambient 20 degrees but at least sunny. I do have the advantage of the water tank located within the house under the bed, and holding tanks enclosed above the chassis frame rails beneath the bedroom and bathroom floor(s).

Driving down the road, exhaust and rear axle heat will convect very well up through the floor, so no freezing issues at pretty much any east coast outside temp. When stopping overnight, I always have the goal of getting south enough to be above freezing. That hasn't always been the case, but with where my tanks are as well as running the house furnace, which has perforated ducts through the holding tank area, I've never had any issue even with temps in the low 20's.

I've also stuck a ceramic heater in the compartment where the water pump and low point drain plumbing is in super cold weather; there's an exterior 110v outlet not far away, routing the power cord through the door only latching one side, and run the generator overnight to blast the plumbing with heat. That arrangement I'd guesstimate would be good down to about 0 degrees in mine.
