2-Stage Auto Changeover RV Propane Regulator with QCC1 Hose - Reliable

In this review of the 2-Stage Auto Changeover RV Propane Regulator with QCC1 hose, the reviewer finds it best suited for RV owners and campers who need uninterrupted LP supply and an easy swap to a reserve tank. The single biggest reason to buy is the automatic changeover plus built-in rotary indicator and gauges, which together keep appliances running when one tank runs low and make refill timing clear. Installation is straightforward and the package includes hoses, tape and a wrench so most users can fit it without extra parts.

Key Features

• Automatic changeover: Switches from primary to reserve tank without interruption so heaters and appliances keep running when one tank empties.
• Dual tank support: Connects two refillable 5-40 lb propane tanks simultaneously to maintain continuous fuel delivery while traveling.
• High-capacity delivery: Provides up to 210,000 BTU/hr from the primary side and 130,000 BTU/hr from reserve for grills and RV heaters that demand higher flow.
• Rotary pointer and color indicators: The selector shows which tank is active and gives a visual refill alert so you can plan replacements.
• Complete kit: Ships with two 18' stainless braided QCC1 pigtails, roll tape and a wrench so you have all pieces needed for installation.

Who It's For

This regulator is ideal for RV owners, camper van users, and travel trailer operators who rely on continuous propane for cooking, heating, or running appliances and want an automatic backup without manual tank switching. It suits anyone replacing an existing automatic changeover regulator or adding dual-tank capability to an RV fuel system.

It is less suitable for users with single disposable cylinders or systems that require uncommon fittings; the product assumes 1/4 SAE inverted flare inlet connections and a 3/8" female NPT outlet, and those with custom plumbing may need adapters or professional installation.
