Buying Guide: How to Choose a Dual-Tank RV Gas Regulator
- Two‑stage vs single‑stage: Two‑stage regulators provide steadier gas pressure, reducing fluctuations as tanks deplete. This is especially important for sensitive appliances like stoves and heaters.
- Automatic changeover: Look for regulators with a reliable auto changeover between service and reserve tanks. This minimizes propane interruptions during trips.
- BTU rating and 11″ WC output: Ensure the regulator’s master and reserve BTU/hour ratings meet your RV’s total propane demand and maintain a steady flow at 11 inches of water column.
- Hose quality and fittings: Stainless braided hoses resist wear and corrosion. Check that hose lengths fit your vehicle’s storage and mounting space and that fittings match your tank valves on both tanks.
- CSA/UL certifications: CSA certification is a strong indicator of safe, reliable components for RV gas systems. Include hoses, regulators, and connectors in the approval scope.
- Cold-weather performance: High‑volume regulators designed for cold mornings help prevent pressure drops and clogs. If you camp in winter, prioritize high‑flow cold‑weather capable units.
- Installation and inclusions: Some packages include hoses, wrenches, and sealing tape. A complete kit can simplify installation and reduce the need for additional purchases.
