Yosemite is extremely popular. It is not an area with parks designed for today's rigs. In the past, we've stayed at both the upper campground at Lake McClure & the fairgrounds in Mariposa. Both have at least partial hook-ups but may only be 30 amp. Pull-thrus are unlikely. The Lakes RV in Chowcilla is gorgeous but is a long drive out. We've done that also. We did not care for Marina RV. The summer we did a drive thru they had tent sites at the back of the back in sites. No thanks. There's a KOA at Moss Landing we used before it was a KOA. (I avoid West Coast KOA's.). We use Betabel RV on 101 to access all the highway 1 stuff. And most definitely keep the RV off 1. Great with a dinghy.
