For those who think that there is not a lot of RV action in colder parts of Canada, all one has to do is drive around and observe.
Take one cold winter location for example: Calgary. We see temperatures frequently in the upper minus 20's and lower 30's C. Sometimes more extreme. Short as they may be, our summers are blistering hot. Our igloos melt and we have to build straw huts.... :W:W
Take a drive around the outer city areas and down any highway. There is storage yard after storage yard after storage yard, everywhere you go. Thousands and many more thousands of RV's stored everywhere you look.
It's most likely the same for any major city, such as Regina.
My work takes me all over the map, so I not only see this, but I also see lots of them on the road in all kinds of cold adverse weather. We have a few unserviced locations that are accessible year round, some with power only for obvious reasons.
The point is there are many considerations to be out winter camping and batteries are one of them. We have to consider the effects of cold and what will give us optimum service when it is well below freezing.
Some types of batteries are just not well suited for extreme cold. My GC2's last all winter, outside in the RV. They will still function, run out the slide in any weather.
We are not talking Florida here where you don't get real winter. It's about making it work in cold parts of Canada.
