Take time to read some of the reviews - this is one of the more highly reviewed campsites on Campendium so there is lots of good information here. There are always a good number of people here, but they come and go on a daily basis and it is a pretty big area so finding a place usually isn't difficult, though many are better than others. I was there last September and enjoyed it immensely as most people do. As for your camper...it all depends - you'll just have to work with it but some source of heat is always a good idea. The thickness of the walls/floor, the amount of insulation, the weather/wind, the number of slides you have, and how well sealed they are, etc. Covering the windows with silver reflecting insulating panels can help a lot. Hope this helps.
