I am not sure
I don't know if you are allowed or not, but I'll share some information. There are only 11 sites at the campground. When making reservations, you can't reserve a spot. Most of the sites have wooden railings around them and some you have to cross over a walking bridge to get to. Campsite number 1 is really the only one you could even get a pop-up into. Again not being able to reserve a spot I'd advise against it.
Call the Ranger station in Wartburg. They are fantastic and the center is open a lot. Hardly ever busy but they are so helpful with maps, directions and such.
I am not sure about that, sorry,
