The numbers that decide it
Recreation.gov publishes no site-level detail for this campground, so we cannot say what length of rig it takes. Call the managing office before committing to it in a large vehicle.
Site-level RV detail confirmed against Recreation.gov. Where a field says "not published," the agency has not published it — it does not mean zero.
