You just don't seem to grasp the obvious,, put on a warm coat and see that it works,, BECAUSE IT IS HEAVY FOR A REASON.. Now add all the items that have to "gain weight" for the same reason..
We see your kind of reasoning every day on the forum.. Not only is winter climate cold,, but altitude and wind makes it colder yet.. The altitude and cold temps makes LP gas almost useless,, look at the number of windows in the average camper and see another major problem with your notion...>>>Dan ( Studies have shown a range reduction of 20% and more in cold to very cold weather with the average EV,, throw in the defroster,, heater,, lights and a heavy load and you will be walking very soon..) ( we live at 6000 feet at the base of a 12000 mountain in Utah,, we know cold.)
