The short answer is "lots and lots of people".... Here in the States, there are lots of folks living in their caravan (Recreational Vehicle, RV here). Mostly retired folks who have an RV and travel South to North US avoiding the winters of the north and the heat of the south during the summer. Many temporary workers move from site to site over a multiple month period, will live in their trailers for years at a time. My wife and I just finished a program called Workampers helpers. We are given a free seasonal site at a campground whilst we work a few part time hours for the campground to pay for our visit. Works out for everyone.
