We camped at the south rim trailer village in early January a couple of years ago. It was very cold and snowed the last 2 days we were there. Water froze in the campground supply but we had an almost full fresh water tank so no issues. One area of concern was that the roads inside the campground were not plowed while we're we there. If it wasn't for having 4 wheel drive I don't think I could have pulled the trailer out of the campsite. Once out of the campground roads were plowed and clear. However, the Grand Canyon in snow is really beautiful and we almost had the place to ourselves. I would highly recommend braving the elements to experience it.
