First off, your coach is what my wife is currently looking to upgrade to! As others have said, this is a dry year so far in California, but that could easily change. For a coach your size, I'd suggest you consider staying at a nice private park in the flatlands & using your dinghy for day trips. Last fall we used Country Manor in Visalia to access King's Canyon & Sequoia. We had used Sun & Fun previously in Tulare. Both okay. 8/10. The Lakes in Chowchilla is great. We access Yosemite from there. We've also used the fairgrounds in Mariposa & public parks at Lake McClure - Horseshoe I think. It's the 'new' upper one that has a view of the lake. Easter the public parks will be packed. Yosemite will be a traffic nightmare. Lassen, truly one of the underrated parks, is spectacular. And relatively uncrowded. Typically the road thru it won't open until June/July, but you can easily access most of the park via Red Bluff & Redding. Both of which have 10/10 private parks. While in the Redding area, Burney Falls is worth a day trip. The redwoods are best accessed from Redding over to Eureka. In our 37' Winnebago, it is a full day's, scenic drive. We then stay at either Mad River RV in Arcata or Sounds of the Sea in Trinidad. If you want to see the redwoods south of Eureka, from Redding head south on I-5 & access them by cutting over around Clear Lake and then head north. Ancient Redwoods RV, if open for the season, is another 10/10 park. Then just head north along the coast. As you can see, we prefer the high end full hookup places, then take the dinghy on day trips. Finally, if you come up through Bakersfield (lots of nice private parks!) then head north, snow will only be a problem near the parks themselves if we do finally get some precipitation this year. I had my old full time 4wd drive Grand Cherokee in both Sequoia & Yosemite in snow flurries but full sunshine in the parks we were staying at at the lower elevations. Keep in mind, when school is not in session, all of these places are very popular.
