This campground is sparse in amenities and full of the beauty of the eastern Sierras. The sites are really optimized for car or tent camping, but will also work for a small trailer. We have a 13 foot vintage travel trailer and she fits anywhere, but not all of the slabs were level or easy to back into. The sites are large and most of them have a pretty view, or an interesting rock formation.  They are spacious and there is plenty of room from your neighbors.     
We went in July and there were no attendants on site, and they are all first come first served. You put your fees (cash or check) in an envelope at the entrance and tear off a flap to clip at your site while you are there, as well as a hang tag for your vehicle. Its $17 per site and I think an additional $7 per extra vehicle The toilets are vault toilets, and there are water taps every few sites but the notice said that the water was not potable until boiled for 5 minutes. There are no showers, and no trash bins - you pack your trash out.
There is no cel service - we had none until the bottom of the 9 mile grade where you start the climb 30 miles away. There is a general store that has ice and drinks about 35 minutes / 9 miles from the campsite towards Kennedy Meadows, and Grumpy Bears retreat about 2 more miles down the road that has food and a bar. Both the general store and Grumpy Bears have a decent wifi that you pay for. I used the 2 hours for $2 and that was enough to get messages out and catch up.

The only gas for sale that I saw was at the general store, and it was expensive, but nice to know its there. There is a trash dumpsite on the turnoff before Grumpy Bears.

We stayed for 5 days and I could have stayed much longer!
