100% winter. You’ll see up to about 30% drop in range at single digit temps. Do you monitor the efficiency screen at all ? I rarely trust the general soc- the trip finder will always adjust as range varies depending upon travel efficiency levels
Did same as @wjhdrew - Rmaxx via their recommended “cut a hole” method. Fairly Easy process with good docs and hole templates. Took a couple of hours and my 5’2” wife is much happier now ?
