I know that everyone loves staying in their little FG camper, but check out this campground. You can rent and stay in several different vintage trailers. Of course, you can also bring your own camper if you'd rather. Looks like a beautiful area. Website says the park will have their Grand Opening on April 16th. They're located near Canyon City, CO.
Seems like a nice use for those old trailers since they'd probably loosen up and leak if you pulled them around too much. By the way, that town is called Caņon City.
