Tent trailer full-time...?

Has anyone had the experience of living full-time in a pop-up tent camper. They have several amenities that would seem to make them livable/doable, such as heaters and air conditioners. I have been homeless for over a year living in my pick-up so anything else would be an improvement. I am starting a new job with a very good wage and could certainly save the money for the investment in no time. What do RV campgrounds typically charge for lot rent? I assume it is seasonally adjusted. Any insight is very appreciated!
