Hooking up a camco rv external propane tank adapter kit is honestly one of those small upgrades that completely changes how you camp, especially if you hate the idea of driving your entire motorhome to a refill station just because the furnace ran all night. If you've ever been cozy in bed only to realize the heat just kicked off because the onboard tank is bone dry, you know exactly how annoying that situation is. It's not like you can just pop out and fill up a fixed tank in five minutes when you're already leveled and hooked up at a site.
That's where this specific kit comes in. It's often called an "Extend-a-Stay" setup, and for good reason. It sits right between your main tank and the regulator, giving you a way to plug in a standard 20-pound grill bottle. It's a simple piece of brass, but it solves a massive logistical headache for anyone who spends more than a weekend in one spot.
Why this kit makes life on the road easier
The biggest hurdle with motorhomes is that the propane tank is usually bolted to the chassis. You can't just take it off. If you're staying at a park for two weeks and it's chilly, you're going to burn through that propane. Without a camco rv external propane tank adapter kit, your only option is to unhook your water, pull in your slides, disconnect the power, and drive the whole rig to a propane dealer. Nobody wants to do that.
With the adapter installed, you can just keep a spare 20lb tank in the back of your truck or a storage bay. When the main tank gets low, you hook up the portable one, and you're back in business. Plus, those small tanks are everywhere. You can swap them out at almost any gas station or grocery store. It's the ultimate "peace of mind" insurance policy against freezing in the middle of the night.
Another thing I really appreciate is the flexibility it gives you for outdoor cooking. Most of these kits come with a secondary port. This means you can run a hose directly to your portable tabletop grill or a fire pit without needing to carry a separate heavy tank just for the BBQ. You're essentially tapping into your RV's main supply or the auxiliary tank to feed your burger-flipping habit.
What's actually inside the kit?
When you crack open the box, you're going to see a few specific components. The star of the show is the brass T-piece. This is what actually stays on your RV full-time. It has a couple of different ports on it, usually covered by plastic caps to keep the spiders out (and trust me, spiders love propane smells for some reason).
You'll also get a couple of hoses. One is typically meant for connecting that external 20lb or 30lb "BBQ style" tank to the T-fitting. The other one is usually a longer hose meant for connecting a high-pressure appliance, like a portable stove or a grill. It's a pretty straightforward setup, but it's important to remember that this isn't a "one size fits all" for every single gas appliance. It's designed to work with the high-pressure side of your system before it hits the RV's main regulator.
Getting the installation right
Putting the camco rv external propane tank adapter kit on isn't a job that requires a master plumber, but you do want to be careful. After all, you're dealing with flammable gas. The first thing you've got to do is turn off the main valve on your RV's propane tank. Make sure there's no gas flowing through the lines.
You'll usually need a couple of adjustable wrenches. You disconnect the pigtail hose that goes from your tank to the regulator, and you sandwich the Camco T-piece right in the middle. It's all threaded, so it should screw right in. One big tip here: don't over-tighten it. Brass is a soft metal, and if you go full-strength on it, you can crack the fittings or strip the threads. Just get it snug.
Once it's on, the real test begins. You'll want to turn the main gas back on and do the "soapy water test." Just mix some dish soap and water in a spray bottle and douse the connections. If you see bubbles growing, you've got a leak and need to tighten things up or check the seals. It's a five-minute safety check that saves you a lot of worry later on.
Using the auxiliary tank feature
Once the hardware is installed, using an external tank is incredibly simple. You just take your portable bottle, set it on the ground near your propane compartment, and connect the provided hose from the bottle to the T-piece.
The cool thing about how this works is the pressure. When you open the valve on the external tank, that gas flows into the T-piece and then through your RV's regulator. You don't even have to turn off your main onboard tank if you don't want to, though most people do it to ensure they are strictly pulling from the portable one first. It allows you to "save" your big tank for when you're actually traveling or can't get to a store to swap the small one.
I've seen some people get confused about whether they need to change their interior settings. You don't. Your furnace, fridge, and stove won't know the difference between the gas coming from the big permanent tank or the little one sitting on the grass outside. It's all the same to them once it passes through the regulator.
Cooking outside with the kit
Let's talk about the second hose for a minute. Most people buy the camco rv external propane tank adapter kit for the stay-put convenience, but the grilling aspect is a huge bonus. If you have a grill that normally takes those little 1lb green disposable canisters, you can use this kit to run it off your RV's supply instead.
It's way more cost-effective than buying those little green bottles, which seem to get more expensive every year and always run out right when the steak is half-done. Just keep in mind that the port on the Camco adapter is high-pressure. This means it's meant for grills that have their own built-in regulator. If you try to hook up a grill that's already been modified for a "low-pressure quick connect," it won't work right. But for your standard out-of-the-box portable Coleman or Weber, it's usually perfect.
A few practical tips for the road
If you're going to be using this setup often, there are a few things I've learned the hard way. First, keep those plastic dust caps on the T-piece whenever a hose isn't connected. Mud daubers and other bugs love to crawl into those openings and build nests. A clogged propane line is a nightmare to clear out when you're just trying to get some coffee going in the morning.
Second, think about where you place your external tank. You want it on a flat, stable surface. Some people buy a little plastic base for their 20lb tanks so they don't tip over on uneven dirt or grass. If a tank tips, it can liquid-slug the regulator, which isn't great. Also, make sure your hose isn't a tripping hazard. If someone catches their foot on that hose, it can put a lot of stress on the brass fittings.
Lastly, always check your O-rings. The hoses that come with the kit have rubber seals. Over time, especially with heat and cold cycles, those seals can dry out or crack. A quick visual inspection before you hook up can prevent a lot of wasted gas and "smelly" surprises.
Is it worth the investment?
In the world of RV gadgets, there's a lot of fluff. But the camco rv external propane tank adapter kit is one of those utilitarian tools that actually delivers. It's not flashy, but it removes one of the most annoying "chores" of motorhome ownership.
If you're a weekend warrior who only stays at parks with full hookups and rarely uses the furnace, you might not need it. But if you enjoy boondocking, stay in colder climates, or just want the flexibility of using exchangeable tanks, it's probably the best fifty or sixty bucks you'll spend on your rig. It gives you options, and when you're living in a box on wheels, options are the key to staying comfortable.
It really just comes down to making the RV work for you, rather than you working for the RV. No one wants to pack up their entire house just to go get a few gallons of propane. With this kit installed, you just grab the small tank, throw it in the car, and go—leaving your campsite perfectly intact.
