22 campgrounds that take vehicles of 40 feet or more in Mississippi

The Army Corps of Engineers and the Forest Service run nearly all of them. National Forests in Mississippi and Tennessee-Tombigbee Waterway hold more of them than anywhere else in the state. Wallace Creek takes the longest rig in Mississippi at 141 feet.

A campground is listed when the longest permitted vehicle in its Recreation.gov site records is 40 feet or more. The figure is the longest single site, so most sites at a listed campground are shorter.
