When selecting a hose for your RV water supply, prioritize features like "drinking water safe" labeling to avoid harmful chemicals, a suitable length (typically 25-100 feet) for easy reach, and durable materials such as kink-resistant vinyl or rubber. Make sure the hose can handle standard water pressure (100-200 PSI) and remains flexible in various temperatures. Look for hoses with anti-kink designs, UV protection for sun durability, and rust-resistant fittings like brass or stainless steel. Additionally, choose one that's easy to store, whether coiling or retracting, to keep your RV setup hassle-free. Sandiario
