Just to add. I heat the cabin mainly for the fridge. If the ambient temperature is too low, the freezer contents melt while the fridge contents freeze. Also my fresh tank is under the bed.
Lastly, in my book there's a difference between cold weather transit and a long duration trip.
If I were snowbirding to Florida from Michigan I would consider that transit. I'd likely be winterized, go out to eat when stopping for the night and not use any onboard facilities.
However spending a month (or more) living in the unit, I want everything I paid for working. Flushing toilet, washing dishes, taking a shower, etc.
