Well, one issue that comes with camping in California, is that most of the state park campgrounds have few, if not none, for RVs 30'+.
Having camped all over California for 30 years, your choices for places for larger RVs will be more limited.
The California State Park system has done very little to revamp their campgrounds for today's larger RVs.
Best bet will be private parks or state beach campgrounds.
If your preference is public/state parks, you might want to look at 3 bed hybrid trailers.
Sleeping for up to 10, in something like the Roo/Shamrock 233S, in a lighter 25' package.
We've owned a hybrid TT for almost 10 years and consider it perfect for California camping.
