Best Auto Changeover Propane Regulator For RVs In 2023

1. Best Overall – Flame King (KT12ACR6a)

The Flame King is one of the few products that can differentiate itself in this category. Apart from its sleek design and build, the white cover for protection, and front-mounted regulator knob, it is also one of the few regulators that also come with its own mount.

The Flame King also offers a 90-day warranty. It can handle 190,000 BTUs of propane at 11″ wc of pressure. It can automatically switch tanks when one tank gets emptied and has a color indicator to show that the tank is emptied.

What We Liked

• One of the few products that come with its own cap for protection from the weather.
• The regulator includes a mounting panel for RVs.
• It has a 90-day warranty, and the customer service is quite good.

What We Didn’t Like

• It can only handle up to 190,000B BTU/hr of propane flow. So if you are using a cooktop with a large number of burners, it might not be able to handle the flow.
• It is a heavier regulator than its peers, so one more mounting screw would have helped.
• The pigtails that come with the regulator are not as durable.

Camco is one of the most trusted and reputed brands in the RV industry. They have been around since 1966 and hold more than 140 patents for products that are of everyday use in RVs.

Camco’s 2 stage changeover regulator follows the tradition of that same trust. With a one-year warranty, quality customer service, and a durable product, Camco has a winner product that is perfect for your RV with two propane tanks.

It can handle up to 210,000 BTU/hr from the primary tank and 130,000 BTU/hr in the reserve tank. It also has a color change indicator built into the regulator knob, which tells you that your propane tank is empty and the device has automatically started using the second cylinder.

What We Liked

• Camco’s trust factor and quality customer service are significant reasons for buying this product.
• It is one of the few products that come with its mounting screws included. It’s straightforward to install on your RV.
• It provides steady gas pressure of 11″ wc and is better in this respect than cheaper regulators.

What We Didn’t Like

• It does not come with its mounting bracket, so if your RV’s old mounting bracket does not fit, you will have to buy a new one from the market.
• Every once in a while, you might get a product from Camco that makes noises when you use it, indicating potential leaks. Always check with soap water for bubbles to ensure that the product has no leaks.
• The red and green indicator is a bit difficult to see in direct sunlight.

Marshall Excelsior products are considered the most long-lasting LPG and NH3 equipment in the market, and the MEGR-253 is no exception.

The MEGR-253 has a Zinc body with an exterior powder coating. The diaphragms are made from reinforced and molded fabric and have a body seal on the O-ring bonnet. This is what makes this product extremely durable. Marshall Excelsior even offers a five-year warranty on the product (however, only through authorized resellers).

You can get 225,000 BTU’s/hr from your primary propane tank and 150,000 BTU/hr from the reserve one with this regulator, all at a steady 11″ wc. Marshall Excelsior also makes the mounting brackets and waterproof cover for this product, which you can buy separately.

What We Liked

• Zinc and powder coating makes this product resistant to wear and tear, corrosion and weather. 
• It’s got a strong reputation in the market and a five-year warranty to back it up.
• It can provide a high flow rate of 225,000 BTU/hr, so this is a good option if you need a better flow rate.

What We Didn’t Like

• It’s pretty expensive, perhaps two to three times more than some of the products on our list.
• Does not come with mounting screws, brackets, or cover. You have to buy all of them separately.

While the MEGR-253 does have a strong flow rate, it’s not the best in the market. If you have things that require a lot of propane (like multi-burner stoves), then Fairview’s 2 stage regulator is what you should be looking at.

With a high flow rate of 262,500 BTU/hr, this regulator will let you run appliances that need some serious fuel for their operation.

It is also well built, with the body made from die-cast Zinc and the diaphragms made of molded rubber. The outer body is powder coated, and it even comes with a year’s warranty.

What We Liked

• It has the highest flow rate for 2-stage auto regulators in the market. 
• Despite the high flow rate, it can maintain a good 11′” wc of pressure.
• The regulator is very solid and resistant to corrosion and wear and tear.
• It has dual-color change indicators that let you see the status of both tanks simultaneously.

What We Didn’t Like

• It’s a heavy piece of equipment; it weighs 2 pounds. 
• It doesn’t come with mourning screws, bracket, or plastic cover
• It’s the second most expensive item on our list.

If you are looking for something lighter and cheaper, the JR products 07-31525 is about three-quarters the size of its peers but is just as good. It also has a solid 262,500 BTU/hr flow rate, giving the Fairview product a run for its money.

This product has almost all the features of the Fairview option. It also has dual-color indicators and is made with powder-coated zinc. You can buy the mounting brackets and plastic cover separately.

What We Liked

• Its got a higher flow rate than other regulators in this lineup, but it is still one of the cheapest products around
• It is much lighter and smaller than other regulators
• It is durable, made with powder-coated, die-cast zinc
• It is pretty inexpensive compared to similar options

What We Didn’t Like

• It does not come with mounting brackets or screws.
