Blaine spotted this really neat model of a Jeep CJ-5 Camper setup. It’s pretty neat model and unique model that I believe is about 3″ long. It is shipped from Mannheim, Germany. In the post below this one, there’s some history about the camper inventor.

If you are concerned about postage and the like, it MIGHT be available from one of the larger online U.S. diecast stores.
