It happened to us at a state park, we could not get in without hitting an old dead branch so we went to the office and explained it to them. The response was someone was just in there and had no problems. I responded with yes it was a popup camper..just come to the site and look. The staff did come right out, saw it and agreed the branch had to go, was in the way etc and cut it off right then. I would have never done that myself.
