I called the local Ranger station for Moab / Arches and they were very helpful about campground conditions. You may have to park away from the RV if allowed. The Rangers don't run the campgrounds but have to police them so they are the ones who would ticket or tow. Don't forget to write down the name and date of the call, just in case.
