Serving RVers Around Custer & Custer State Park
From campgrounds inside Custer State Park (Sylvan Lake, Legion Lake, Blue Bell, Game Lodge) to Custer/Mount Rushmore KOA, Beaver Lake Campground, and sites along Needles Highway and the Wildlife Loop, we travel to your location. Custer sits at the heart of the Black Hills — the natural base for Wind Cave National Park, Jewel Cave, Crazy Horse Memorial, and the drive up to Mount Rushmore and Rapid City.
What We See on the Road Here
The climbs and switchbacks on Needles Highway and Iron Mountain Road are hard on brakes, cooling systems, and hitch/coupler hardware — especially on trailers and fifth wheels not built for mountain grades. Generators running AC through Black Hills summer heat at full-hookup and dry-camp sites inside the park are a steady source of surge and no-start calls, and the elevation change from the plains into the Hills is a common trigger for propane appliance and regulator issues.
