Your next step
Buffalo Gap National Grassland Dispersed posts no rig-length limit, so the size of the motorhome is your call rather than the campground's. If you don't own one, the same trip runs on a rig rented in South Dakota.
Nothing in South Dakota is bookable today — PickRV opens for bookings on October 25. Dated requests are what we take to owners, so give us the window you actually want — you get one email the day a rig covers it, and nothing else.
