Fairview GR-9984 RV Propane Auto Changeover Regulator - Reliable LP

In this review the Fairview GR-9984 emerges as a practical solution for RV owners who need an uninterrupted propane supply while traveling. Designed as a two-stage automatic changeover regulator, it keeps appliances running by switching from the service tank to the reserve tank without manual intervention. The biggest reason to consider it is its high capacity and steady low-pressure output, which suits campers and travel trailers that rely on consistent LP flow for cooking, heating, and hot water.

Key Features

• Automatic Changeover: Automatically switches to the reserve tank when the active tank is depleted, maintaining continuous propane for appliances.
• Two-Stage Regulation: Reduces high tank pressure to a steady 11' WC so burners and heaters receive consistent low-pressure flow across the LP system.
• High Capacity Flow: Handles up to 345,000 BTU and 260,000 BTU on the reserve tank per hour to meet heavy demand in larger RV setups and cold conditions.
• Clear Status Indicator: The color indicator shows when the active tank is empty, making refill timing obvious and simple to monitor on the road.
• Standard Connections: Dual 1/4' inverted flare inlets and a 3/8' FPT outlet fit common RV hookups for straightforward installation when using the required hoses and bracket.

Who It's For

The GR-9984 is best for RV, camper, and travel trailer owners who want an automatic solution to avoid losing propane power while driving or camping. It suits users with multiple tanks who need a dependable low-pressure feed for cooking, heating, and continuous hot water on chilly mornings.

Less suitable are owners with very small single-tank setups who do not need auto changeover or those who require an integrated mounting kit, since mounting screws are not included and this listing specifies 14 inverted flare hoses and a bracket extra for installation.

Pros & Cons

Pros

• Reliable automatic switching keeps appliances running without manual tank swaps.
• Two-stage regulation provides stable 11' WC output for consistent appliance performance.
• High flow capacity performs well in cold weather and under heavy LP demand.
• Simple status indicator makes tank monitoring quick and clear.

Cons

• Some customers reported durability concerns and occasional leakage, so long-term reliability can vary.
• Mounting hardware is not supplied and installation requires 14 inverted flare hoses plus an extra bracket as stated, which adds to cost and effort.
