Where can I find used campers for sale, already set up, near Washington, nc?

There's also campers set up for sale on Swan point road

What do you mean by "already set up"? All campers including used ones should be ready to go camping just add your stuff. (if they are not a fixer upper) now it you mean a permanent position camper I suggest you go to a campground and ask the office staff.

U might call goose creek campground also

Twin Lakes Campground just outside little Washington has campers in there all set up possibly somebody would be selling one big Campground
