Traveling to CA from TX - 40' Motorhome

Hey all. We will be traveling to CA from San Antonio in late September. Right now our stops include 2 days at Faywood Hot Springs in NM, 2 Days at Mira Vista in AZ, 2 Days at Shangri La in AZ. We want to spend a day in Palm Springs before heading out to Glen Eden for 3 days but can't seem to find any clothing optional locations in the area with RV slots.

Does anyone have recommendations for locations in that area which might work for us?

Thanks,
Mike & May
