Tuolumne Meadows Campground, Yosomite experience?

There is a dump station near Tuolumne Meadows, available only in summer. https://www.nps.gov/yose/planyourvisit/rvcamping.htm

I saw some Class A's at that campground, tucked very tightly between trees. Don't know how they did it.

I've camped there without reservations, usually in last week before the camp closes in September. Beautiful place. A very different Yosemite from what you see in the valley.
