Where I hunt in Idaho there are campers (travel trailers and 5th wheels) that are set up by the end of July in the bottoms along the main road. Many of them do not pull out until the snow flies or later. There is one camp that is ALWAYS there. Earliest I've gone in scouting is the 2nd week in July (too much snow before that) and they are there. Latest I've been in there was late November and they were still there. I am guessing they leave it there all year. I think on NF land, which this is, you are not supposed to have a camp set up for longer than 14 days, then need to move it a few miles minimum, but the rule is never enforced.
