Our first new Motorhome was a 29' 1997 Winnebago Minnie Winnie, we loved that Motorhome. We took a few years off from motor homing from 2000 to 2005 because of being tied down to our Dairy. In 2006 we purchased a Fleetwood Tioga from my Cousin who owned a Fleetwood dealership. We have since owned a couple of used Born Frees and now our Cruiser.
We have always kept our Motorhomes plugged in when not in use, stored under roof in one of our barns. We have had some coach batteries that needed to be replaced over the years but for the most part we have not had any problems with pipes freezing or battery trouble.
I realize there are varied opinions and different ways to care for our coaches and mine may not be the best, so far we have been very fortunate. Earlier in the week when we spent the night in NY we were plugged in throughout the night at our campsite. The temp dropped to about -4.
The next day we were parked at White Face Mountain in Lake Placid. When we arrived at 8:30 am it was about -8. We chose to run our Generator while we were skiing. We had two small electric heaters running and the furnace set to about 60 degrees.
When we returned to the Cruiser at 3:00 in the afternoon to my delight the Generator was still running and the temp in the coach was 70 degrees, outside temp was about 15 degrees.
We have spent some nights dry camping in cold and hot weather, generally we run the generator throughout the night when we're not plugged in.
