I clipped this bad boy onto my RV setup and instantly felt like I’d leveled up my camping game. No more rushing to switch tanks mid-cook or wondering if my stove’s about to sputter out—this two-stage auto changeover keeps the propane flowing nonstop.Installation was surprisingly chill—just tighten the pigtails, hook up your tanks, and you’re ready to roll. I love how it seamlessly flips from one cylinder to the next without me lifting a finger, so my morning coffee and dinner grill-outs stay uninterrupted. The regulator’s solid brass body feels built to last, and those 12-inch hoses give me the perfect reach without kinking or fuss.Safety’s clearly a priority here, too—steady pressure means consistent flame control, and I’ve had zero leaks or weird pressure drops even on cold mornings. If you’re hitting the road and need reliable propane backup that handles the heavy lifting, this is your no-brainer pick. Trust me, it’s one less thing to worry about when you’re out chasing sunsets.

The Flame King 2-Stage Auto Changeover LP Propane Gas Regulator is an excellent product! It’s incredibly reliable and ensures a constant, stable propane supply. The auto changeover feature works flawlessly, automatically switching tanks when one runs out, so you never have to worry about running out of propane unexpectedly. The included 12-inch pigtails make installation easy, and the regulator fits perfectly on my RV. Highly recommend this for anyone using propane in RVs, vans, or trailers—definitely a must-have for peace of mind on the road!

Easy enough to install with no leaks. Got a good price here. Way better than camping world

This was original equipment on my travel trailer.There is a ton of confusion regarding the difference between ACR-6 & ACR-2. I reached out to Flame King, directly, and they responded the next day informing me there is no difference and they are both rated at over 345,000 BTU/Hour. If I add up ALL of the propane appliances (i.e., furnace, refrigerator, water heater, and stove) in my travel trailer it all comes up to less than 35,000 BTU/Hour demand total. I never had any trouble with the original unit... I just desire to carry a spare.Again, ACR-6 & ACR-2 are identical according to Flame King technical Support.

This Flame King propane regulator is a game changer for my travel trailer. It’s easy to install, and the auto changeover feature works flawlessly. No more worrying about running out of propane unexpectedly. The included pigtails are a nice bonus. Definitely a must-have for anyone with an RV or trailer.

I am extremely disappointed in this. We bought it last July when our RV regulator failed and started leaking propane. We installed it at the end of the season and didn't get a chance to test it out. This season when we went out to start our camping season the RV was not getting propane. After looking at the regulator the area that is supposed to change from red to clear/green was not changing no matter which tank we turned it to. Both tanks were filled that day so we knew that the tanks weren't the issue. We then had to try to track down another regulator to attempt to fix this issue which we couldn't do because of the time of day. We ended up spending the night in 40 degree weather with no heat. Once we did get a regulator the next day we ended up having to purchase one without the pigtails for the tanks, figuring we could use the ones off of the regulator purchased here.When we got the hoses off we were quite surprised by what we discovered. It appears that during the manufacture process the hoses were defective. Within both hoses the connection between the hose and the regulator was plugged. One side had an excess of red material which I'm assuming was used as sealant for the connection. The other side had a metal part blocking the opening between the hose and the regulator. This caused both feeds to the regulator to not function causing us the problem. I am quite surprised that during the quality assurance portion of the manufacture process that this was not discovered and I'm very disappointed.

This product performs perfectly, with a straightforward installation process and excellent quality. I highly suggest it for anyone looking for a trouble-free propane setup!
