I always keep the slides in during winter. We get a lot of snow here, so I don't want it accumulating on the slide awnings, and the driveway is sloped too much to get it completely level anyway. Also, having the slides out makes it more difficult to get close enough to the coach to clear the snow off the roof, and the wind can sometimes be heavy. I plug it in only when I need to recharge the batteries, but keep the cord connected unless I need to take it out. I do winterize, run the generator once a month, check the batteries regularly, and take it out occasionally for a brief run if weather and road conditions allow. I also keep the shades down so the sun doesn't fade or damage the interior.
