Rio Bend looked old and rather worn out to us. We stayed at Sunbeam Lakes RV just on the other side of I-8 for a couple days.
Sunbeam Lakes is kept neat and desert landscaped. The sites are not too close together without much shade but the pool is beautiful. We don't know about activities but the in-pool volleyball players were all having a great time. The biggest downside to Sunbeam (and probably Rio Bend also) is salty water due to agricultural production nearby. Sunbeam had a fresh drinking water dispenser.
