quiet??Tuolumne Meadows closest campground or elsewhere?

There are Forest Service CG outside the Tioga Pass gate, you'd have to check if they are available. Most likely they may have a vault toilet and nothing else. But they are the closest on that side of the park. I would be very surprised if you could get a 30 footer into Toloumne Meadows CG. Maybe a site on the outside edge? But the roads in there make the roads in the valley CG look like freeways. We barely got a 16 ft popup in there many years ago,
