What You'll Learn
The correct equipment for an external propane hookup
Hooking up an external propane tank to your RV can be a challenging process if you don't have the right equipment. Here is a list of the essential items you will need to get the job done:
Extend-a-Stay Propane Kit
First, you will need an Extend-a-Stay adapter, which will connect your RV to an external propane tank. This adapter will become a permanent fixture, upgrading your standard propane system and giving you the flexibility to stay longer in one parking spot. The Extend-a-Stay kit typically includes a four-port brass tee, allowing you to connect to an external propane tank and a gas grill. Opt for a kit that includes an RV propane adapter for a hassle-free installation process.
Wrenches
You will need a set of wrenches to tighten various connections during the installation process. Ensure you have ¾, 7/8, 5/15, and 9/16-inch wrenches in your toolbox. While you may not need all of them, it is always good to be prepared and have a variety of sizes readily available.
Hoses and Fittings
To ensure proper connections, you will need hoses and fittings of the correct sizes. Here is a list of the essential hoses and fittings you will require:
- 25-foot gas hose with 3/8-inch female flare fittings
- 3/8-inch flare with a threaded fitting
- 3/8-inch flare with a 90-degree threaded bend
- ½-inch threaded shutoff valve
- ½- to 3/8-inch threaded reducer
- ¼-inch male threaded to an ACME fitting
- ½ to ¼-inch threaded reducer
Note that some of these parts, such as the ACME side fitting, may be challenging to find, so plan accordingly.
Step-by-Step Installation Process
Now that you have gathered all the necessary equipment, here is a step-by-step guide to installing your external propane hookup:
Step 1: Turn Off the Propane Valve
Before beginning any work, ensure that the propane valve on your RV is turned off. Propane is a flammable gas, so this step is crucial for your safety. Use the appropriate wrench to tighten the valve, and be aware that certain RVs may have left-handed threads, requiring a counterclockwise rotation to tighten.
Step 2: Attach the External Propane Tank Adapter
The external propane tank adapter will be permanently connected to your RV's propane tank and regulator. First, turn off the gas and detach the regulator from the propane tank. Then, attach one end of the adapter to the propane tank by turning it counter-clockwise. Next, attach the propane regulator to the other end of the adapter, again using a counter-clockwise motion. Ensure that the regulator's vent is facing downward.
Step 3: Connect the External Tank
Fasten a ¼-inch inverted flare end to the external propane tank, using the lengthy hose that should have come with your kit. Connect the P.O.L. part of the adapter directly to the propane tank. At this point, you should be able to use the external propane source for your specific needs, such as connecting to a gas grill or other appliances.
To ensure there are no propane leaks, splash soapy water on the connections. If the fittings are properly sealed, there should be no formation of bubbles.

The process of connecting an external propane tank to an RV
Connecting an external propane tank to an RV is a straightforward process, but it's important to do it correctly to avoid any issues with propane pressure or leaks. Here's a step-by-step guide on how to connect an external propane tank to your RV:
Step 1: Understand Propane Regulation
Propane regulation is crucial when connecting an external tank. RV appliances require low-pressure propane, typically around 11" WC or 0.4 PSI. The propane inside the tank is at a much higher pressure, between 100-200 PSI. Therefore, you need to ensure that the propane pressure is regulated correctly before it reaches your RV's appliances.
Step 2: Check for Regulators
Before you begin, check if your RV and the external propane tank have regulators. If your RV has a regulator, it is usually located near the propane tank. The external propane tank may also have its own regulator.
Step 3: Install a T-Fitting
The next step is to install a T-fitting, also known as an "Extend-a-Stay" or "Stay-a-While." This T-fitting will splice into your propane setup and allow you to connect the external tank. It will also provide an additional connection point for a gas grill or other accessories.
Step 4: Position the T-Fitting Correctly
The positioning of the T-fitting depends on whether your external tank has a regulator:
- If your external tank does not have a regulator, install the T-fitting upstream of (before) your RV's regulator. This ensures that all incoming propane is regulated before being distributed to the appliances.
- If your external tank does have a regulator, install the T-fitting downstream of (after) your RV's regulator. This way, the propane is regulated by the external tank's regulator first.
Step 5: Connect the External Tank
Now, you can connect the external propane tank to the T-fitting using a hose. Ensure that the hose is long enough to reach the tank and that all connections are secure.
Step 6: Check for Leaks
Once you've made the connections, it's important to check for any gas leaks. Spray your hoses and fittings with a soapy water solution. If you see any bubbles, it indicates a leak, and you should tighten the connections or replace any faulty parts.
Step 7: Use Correct Thread Tape
Always use yellow thread tape designed for gas connections. Do not use the white tape meant for plumbing connections.
Step 8: Ensure Fittings are Rated for Propane Use
When installing adapter fittings or connectors, make sure they are rated for use with either high or low pressure, as required.
By following these steps, you can safely and effectively connect an external propane tank to your RV, ensuring a steady supply of propane for your appliances during your RV adventures.

The types of RV propane tanks
There are two main types of RV propane tanks: DOT cylinders and ASME tanks. Here is some more information about each type:
DOT Cylinders
DOT cylinders are the type of propane tank that you typically imagine when thinking about a propane tank. They are cylindrical tanks that are situated vertically on the tongue or back bumper of towable trailers like campers, fifth-wheels, and pop-ups. DOT cylinders are not permanently fixed to the RV, meaning they can be moved or swapped out. They are also often found in pairs on RVs since they are smaller. The name comes from the fact that they are regulated by the Department of Transportation.
ASME Tanks
ASME tanks are most often found on motorhomes and are approved and regulated by the American Society of Mechanical Engineers. Unlike DOT cylinders, ASME tanks are permanently affixed to RVs. They are usually found singularity and positioned horizontally underneath the cabin close to the main entryway.
RV Propane Tank Sizes
Propane tanks for RVs come in different sizes. The two most common tank sizes, especially for DOT cylinders, are 20-pound and 33-pound tanks. 33-pound tanks hold more propane but 20-pound tanks are more common and available. ASME tanks, being permanently affixed to the RV, come in a wider variety of sizes, ranging from as small as 20 pounds to as large as 100 gallons (420 pounds) of propane.
