Not trying to burst whatever bubble your looking into but no matter what your going to buy I think the extreme cold your wanting to winter through is asking too much of any brand, now I'm assuming your living way north of me and after last winter I doubt my fiver with the winter package it has would have done the job here in the farthest southern part of Canada let alone up near Barrie, forget Alberta and the like!! One viable option I saw was a enclosed rv campground, the place had large buildings so you could put your rv inside hooked up to power and water and sewer and live in them. I believe this was done up near the oil sands for workers who came from other provinces to work, pretty slick idea I thought but to try to winter like your looking at really could be flat out dangerous if not just one big P.I.T.A.

Some men look at a problem like this and try
to find a solution. I prefer to figure out whose
fault it is and let them take care of it.
