How to Convert Your RV to Propane: A Step-by-Step Guide

Converting your RV to propane is a smart move that can lead to cleaner burning fuel, cost savings, and better efficiency.

Whether you're prepping for life on the road or setting up for a cozy stay in colder climates, this guide will walk you through each detailed step to ensure a safe and successful conversion of your RV to propane power.

Step 1: Gather Tools and Materials

Before starting, make sure you have all the necessary tools and materials. Here's a detailed list to get you started:

Item Purpose
Propane tanks Choose the size based on your RV's requirements.
Mounting hardware To safely secure the propane tanks to your RV.
Pressure regulator To maintain consistent system pressure.
Copper tubing For routing propane to your appliances.
Tubing cutter To cut the copper tubing cleanly.
Fittings and connectors To securely connect the tubing to tanks and appliances.
Leak detection solution To check for any gas leaks.
Wrench set For various installation tasks.
Screwdrivers For adjustments and securing components.
Propane-compatible appliances or conversion kits To ensure safe operation with propane.
Extend-A-Stay kit (optional) For easy propane tank refilling.
Carbon monoxide detector To detect any gas leaks inside the RV.
Fire extinguisher For safety in case of fire.
Safety glasses and gloves To protect your eyes and hands during the process.
Instruction manuals or guides For reference during installation.
Sealant To ensure airtight connections.

Step 2: Put On Safety Gear

Before you begin, put on your safety glasses and gloves to protect yourself from any potential hazards.

Step 3: Secure Your Work Area

Ensure your RV is parked in a safe, well-ventilated area away from open flames or sparks. This will be your workspace for the conversion.

Step 4: Turn Off All Power Sources

For safety, make sure all power sources, including electricity and any existing gas supply, are turned off.

Step 5: Assess Your Current Setup

Inspect your RV and note down all appliances that will be converted to propane, such as the stove, furnace, fridge, and others.

Step 6: Choose the Right Propane Tank

Select a propane tank that suits the size of your RV and meets your energy needs. Larger tanks may be needed for extensive use or cold climates.

Step 7: Position the Propane Tank

Place the propane tank in a designated area on your RV where it can be securely mounted.

Step 8: Mount the Propane Tank

Using the mounting hardware, securely attach the propane tank to your RV, ensuring it's stable and won't shift during travel.

Step 9: Install the Pressure Regulator

Attach the pressure regulator to your propane tank to control the flow and pressure of the gas. This wil quickly indicate if you have either low or high pressure in the system.

Step 10: Measure Copper Tubing Lengths

Measure the lengths of copper tubing required to connect your propane tank to each appliance.

Step 11: Cut Copper Tubing

Using the tubing cutter, cut the copper tubing to the measured lengths, ensuring each cut is clean and straight.

Step 12: Attach Fittings to Tubing

Secure the appropriate fittings and connectors to the ends of each copper tubing section.

Step 13: Route the Tubing

Carefully route the copper tubing from the propane tank to each appliance location within the RV.

Step 14: Secure Tubing in Place

Use clamps or brackets to securely fasten the copper tubing along its route to prevent movement and vibration.

Step 15: Connect Tubing to Appliances

Attach the copper tubing to each propane-compatible appliance, using additional fittings if necessary.

Step 16: Apply Sealant

At each connection point, apply a suitable sealant to ensure a gas-tight seal and prevent leaks.

Step 17: Test for Leaks

Apply a leak detection solution to all connections and observe for bubbles, indicating a leak. If any are found, tighten the connection and retest.

Step 18: Install an Extend-A-Stay Kit

If using an Extend-A-Stay kit, follow the manufacturer's instructions to install it for auxiliary tank connections.

Step 19: Check Appliance Compatibility

Ensure all appliances have been properly converted to use propane, using conversion kits if necessary.

Step 20: Adjust Appliance Settings

Adjust the settings on your appliances to account for propane's different burning properties compared to natural gas.

Step 21: Install a Carbon Monoxide Detector

Place a carbon monoxide detector inside your RV to alert you of any dangerous gas leaks.

Step 22: Have a Professional Inspection (Optional)

Once the installation is complete, have a certified professional inspect your setup to ensure it meets safety standards.

With the conversion complete, you can now enjoy the benefits of a propane-powered RV, confident in the knowledge that you've taken every step to ensure a safe and efficient setup.

Remember to regularly check and maintain your propane system to ensure its ongoing safety and efficiency. With your RV now converted to propane, you're ready for adventures with a cleaner, more cost-effective fuel source.

Types of Propane Tanks: ASME vs DOT Cylinders

My RV uses one of two types of propane tanks: ASME Tanks and DOT Cylinders. Consider the qualities of each tank type when choosing a setup for your RV.

ASME Tanks

ASME tanks are permanently mounted to the RV. These tanks, used in motorhomes, offer a larger storage capacity and are refilled in place.

DOT Cylinders

DOT cylinders are portable tanks that can be removed for refilling. They are frequently used in towable RVs.

ASME tanks have a longer lifespan and do not require recertification, unlike DOT cylinders that must be recertified every 10 years. The choice between an ASME propane tank and a DOT cylinder depends on my RV type and the flexibility I desire in propane storage and refueling.

Propane Tank Sizes

RV propane tank sizes vary, catering to different needs:

  • 20 lb tanks are the common choice for small RVs or weekend trips.
  • 30 lb tanks offer a balance of capacity and portability, suitable for longer excursions.
  • 40 lb (or a larger tank) is ideal for full-timers who require an extended fuel supply.

The right size for my need largely depends on my RV size, appliance usage, and travel habits.

Benefits of Propane RVing

Using propane in my RV has several benefits:


Propane tanks are designed to be easily transported, allowing me to take extra fuel on long trips.


Propane is widely available, making refills convenient wherever my adventures take me.


Propane-fueled appliances tend to heat up quickly and offer consistent performance.


When compared to gasoline or diesel, propane combustion results in fewer greenhouse gases.

RV Safety and Preventing Propane Leaks

When using propane in our RVs, safety is paramount. Regular maintenance and vigilance are vital in preventing propane leaks which can pose serious risks. I'll guide you through routine inspections and how to handle leaks, should they occur.

Routine Safety Inspections

To ensure the safety of my RV propane system, I perform routine inspections. This means:

  • Monthly Checks: I inspect propane cylinders for signs of wear, rust, or damage.
  • Correct Fittings: I make sure that the inverted flare ends of the gas lines are properly fitted to secure system pressure (displayed on the pressure gauge).
  • Soapy Water Test: I use a soapy water solution to check for leaks—bubbles forming indicate a potential leak.
  • Detectors: I verify that my propane and carbon monoxide detectors are in working order, replacing as necessary.
  • Winter Concerns: During the colder months, I check connections more frequently as they can contract and lead to leaks and low pressure.

Documentation from a certified technician is essential, and I keep a record of all checks and services.

Detecting and Addressing Propane Leaks

When converting RV to propane or natural gas, leaks can be a major safety concern. While installing quality lines made with materials such as copper tubing is essential to avoid unnecessary leaks, it is important to follow safety protocols if a leak is suspected.

If I suspect a propane leak:

  1. No Flames: I immediately extinguish any open flames.
  2. Shut Off Gas: I turn off the LP tank valve to halt the flow of propane gas.
  3. Ventilate: I open windows to allow any propane gas, which is heavier than air, to dissipate.
  4. Evacuate: I promptly leave the RV and ensure all occupants are safely away from the vicinity.
  5. Professional Help: Once safe, I seek a professional to diagnose and troubleshoot the leak.
  6. Cover: To avoid accidental ignition, I avoid using anything that could create a spark, including electronic devices.

I take these proactive steps to guard against liquid propane  leaks, understanding that a careful approach is key to maintaining both my RV and our safety.
