Suggestions for Yosemite Valley RV camping

Lower Pines, site 39 is large enough and has the best view of Half Dome of any valley campsite. If you can get it! Generally it's so hard to get a reservation in the valley, you're lucky to score any site at all. But I was able to reserve one night in that site and a second night in North Pines, just a week or so before my July departure, by going back to the reservation site frequently to see if anything had opened up. People do cancel their sites from time to time, and you just need lucky timing.
