Using RV during MN winter?

[Ivynovich]

Hi everyone! I am a first time RV owner. Bought our 1990 Dolphin in June, so are entering our first winter. We live in the Twin Cities and temps are dropping so after our trip last weekend had been planning to winterize it for storage. However, a friend called and said that he's renovating their house for 3 weeks in November in Duluth and was wondering about parking our Dolphin in his driveway to stay in. It's even colder up there...temps could reasonably be in the 20's that time of year. He would like to be able to use the water/plumbing for convenience sake. I'm a bit naive on the subject but my gut is saying it's not a good idea, even though I really want to be able to help my friend out. Is there any way this is possible? What should I be considering or thinking about with this?

 

Of note, the previous owner removed all propane systems so unless I'm wrong and the furnace doesn't run on propane, the furnace is not functional. I planned to send a space heater along to heat the interior. It does have a working electric hot water heater and he'll be able to plug in.

 

Thanks in advance for your wisdom on this.
