Since we are unfamiliar with your route intentions, I can recommend some that may or may not be on your route. These are from Lodi/Stockton area and then south.
Lodi - Flag City RV at I-5 & 12 is a passport.
Bakersfield - we stay at Orange Grove before either going over Barstow & Tehachapi.
Lancaster has a fairground that was nice last year. Do not remember if Passport or not, but reasonable.
Needles KOA was reasonable this year and very friendly-family owned park.
Banning KOA has always been friendly, but a bit more $$ but, very clean easy in and out.
Cattails State park on A-95 just south of Lake Havasu is awesome.
Currently parked at Desert Gardens in Quartzsite resting up for the rally on Plamosa Rd.
Enjoy the ride and be safe out there!!!
