Winter Camping

Are you planning on staying in a campground? If so, you need to locate one that is open. Most will be closed.

Does nayone know if the furnace in the Winnebago heats the storage area where the tanks are?

Further north in Michigan but you should winterize. For winter camping we keep gallon bottles of water in the bathtub. We use that water for flusing toilets and heating water.
And of course you sometimes get a winter where you have warm spells and could get by without winterizing the week you are camping. I would not count on it.
I bought a coffee percolator at a garage sale that we use for heating water. If we are at a campground with open bathrooms and showers we take our jugs over to fill with hot water there.
My husband wants to fill the five gallon jugs, they are too big for me to handle easily.

I don't live in Ohio but I do live in Lexington,KY and Dec can be a rough month weather wise. Sometimes it's the coldest of the winter months and other times I've even cut the grass in Dec. But I'd have what ever the weather might call for so you won't be caught short handed. But that's just me maybe someone can give you better insight to weather more north as I'm closer to the southern part of OH ..
