As a general rule no unless the appliance is specifically rated for use while moving.
Most RV refrigerators are designed to operate on propane while driving, as they are typically hybrid models capable of running on both electricity and propane. However, the decision to use propane while driving should be based on safety considerations, as the primary concern is the risk of a gas leak leading to fire or explosion, especially if a propane line becomes loose or damaged during transit. While it is generally legal to drive with propane on in most U.S. states, specific restrictions exist in certain areas, such as tunnels, bridges, and gas stations, where propane must be turned off to prevent fire hazards. Some provinces in Canada also have laws requiring propane to be turned off while driving.
To determine if your specific propane appliance can be safely used while driving, consider the following:
Check the manufacturer’s manual for any specific instructions or warnings regarding operation during transit.
Ensure your propane system, including lines and valves, is in good condition and free of leaks before driving.
Be aware that some appliances, like the refrigerator, may be more susceptible to damage if the RV is not level, which can occur while driving.
Consider that even if an appliance is designed to run on propane, it is safer to turn off the propane supply at the tank while driving unless you are certain of local regulations and the integrity of your system.
