Nice so you own the property?
Most of the parks from the Palo Verde Dam to the Agnes Wilson bridge are on Indian land, you lease the land from them and put your own trailer/ garage etc on the leased land. Some areas the land can be owned but they are far and few between, and most of the parks you see along this stretch do not allow RV camping. I believe Lost Lake allows RV parking, but Hidden Valley/ Water Wheel/ Aha Quin/ Point Pleasure do not allowRV camping in their parks.
