Truck Camper Generator: Run While Traveling?

Running a generator while driving is a common practice for RV owners, especially in hot weather, to keep the air conditioning running and ensure the interior is cool and comfortable when they arrive at their destination. It is also useful for powering other appliances such as the refrigerator, microwave, and TV, and for charging the RV's house batteries. While it is generally safe to run a built-in generator while driving, there are some safety concerns to be aware of, particularly if your generator is propane-powered. It is important to check local laws, as some states prohibit the use of propane while driving on highways, bridges, and tunnels, and it is illegal to have an active propane fire when stopping at a gas station. Additionally, generators can affect fuel mileage, as they draw from the same tank as the vehicle's engine, and there is a risk of poor connections and fire hazards with portable generators. Overall, while running a generator while driving can be convenient, it is important to be mindful of safety regulations and take the necessary precautions.

It is safe to run your generator while driving, but you must perform proper maintenance

If your generator runs off of gasoline, it will affect your mileage, and you will go through gas faster while running your generator and driving. Luckily, most generators will shut off automatically when the fuel gets below a certain level, such as a quarter or an eighth of a tank. This will prevent your generator from running out of fuel and leaving you stranded.

In addition to following local regulations, there are several maintenance tasks you should perform to ensure the safe operation of your generator while driving. First, make sure to check fasteners and change the oil regularly. Second, ensure that your generator has enough fuel to operate. Third, keep your generator clean and well-maintained before driving with it. Any engine with a fuel source is a potential fire hazard, so it is important to remove any built-up debris and ensure that the generator is not sprayed with oil. Finally, if your generator runs off of the fuel from the RV's fuel tank, make sure you have enough fuel to reach your destination while also powering your generator. It will take more fuel to do both than just driving from one location to another.

A generator can power your rooftop air conditioning unit, refrigerator, microwave, and electric water heater while driving

A generator is a valuable addition to any RV or motorhome, providing power to appliances and devices that run on 120 volts, such as TVs, stereos, computers, and hair dryers. It can also power essential items like the rooftop air conditioning unit, refrigerator, and microwave. Additionally, it can be used to charge the RV's house batteries, which is particularly useful when driving, as the vehicle's alternator alone may not be sufficient to charge them fully.

When it comes to powering your rooftop air conditioning unit, refrigerator, microwave, and electric water heater while driving, a generator can indeed rise to the task. Here are some insights and considerations for using a generator to power these appliances while on the move:

Rooftop Air Conditioning Unit

RVs are notorious for becoming uncomfortably warm, especially when it's hot outside. By running the generator while driving, you can power the air conditioning unit and maintain a comfortable temperature for passengers. This is a significant advantage over relying solely on the house batteries, which typically cannot power the air conditioning unit.

Refrigerator

While travelling for extended periods, keeping your food cold can be a challenge. Running a generator while driving allows you to keep your refrigerator running, ensuring your food stays fresh and your drinks remain cool. This is especially useful if you're en route to a camping location without access to shore power.

Microwave

Sometimes, you or your fellow travellers will want a quick snack on the go. With a generator, you can power your microwave to heat up meals or prepare a quick bite during rest stops. This is particularly convenient if you're travelling with family or friends who might need a meal on the road.

Electric Water Heater

No one likes a tepid shower after a long day of driving. By running the generator while en route to your camping destination, you can heat up water in your electric water heater in advance. This way, you can enjoy a relaxing hot shower as soon as you arrive and set up camp.

Safety Considerations

While it is generally safe to run a built-in generator while driving, there are some important safety considerations to keep in mind:

• Fuel Consumption: If your generator runs off the same fuel tank as your vehicle, be aware that it will deplete your fuel much faster. Always ensure you have enough fuel to reach your destination while powering your generator.
• Maintenance: Proper maintenance of your generator is crucial. Regularly check fasteners, change the oil, and ensure your generator has enough fuel to operate optimally.
• Propane Usage: If your generator is propane-powered, check local laws and regulations before using it while driving. Some states and regions may prohibit its use, especially at gas stations, in tunnels, or on ferries.
• Ventilation: If using a portable generator, ensure it is well-ventilated and not enclosed. Generators produce heat and require adequate airflow to prevent fire hazards.

If your generator runs on gas or diesel, it will use up fuel faster while driving

This means that your tank will empty much quicker, and you could find yourself running out of fuel if you don't plan accordingly. It's important to calculate how much extra fuel you'll need to factor in the generator, and make sure you have enough to reach your destination.

Most generators will automatically shut down when the fuel level reaches a certain point, usually around a quarter or an eighth of a tank. This is to prevent the generator from running the tank completely dry. So, if you're running the generator while driving, it might shut down unexpectedly as your fuel level gets low.

To avoid this, make sure you have enough fuel to reach your destination while also powering your generator for the duration of your trip. It's also a good idea to perform regular maintenance on your generator, such as checking fasteners and changing the oil regularly, to ensure it runs efficiently and doesn't break down unexpectedly.

Additionally, be aware of local laws and regulations regarding the use of generators while driving. For example, if your generator is propane-powered, there may be restrictions on its use while on the road, especially when filling up at gas stations or driving through tunnels or bridges. Always prioritise safety and follow any relevant guidelines or regulations.

If your generator is propane-powered, check local laws before operating it while driving

If your generator is propane-powered, it's crucial to check your local laws before operating it while driving. The legality of using propane-powered generators while driving varies across different states and regions. Some areas may have restrictions or even prohibit the use of propane-powered devices while your vehicle is in motion.

Propane usage while driving is a highly debated topic, with some people expressing safety concerns. The primary worry is the risk of fire or explosion if the gas line gets damaged during transit. Typically, propane gas lines are installed underneath the RV, so if there is a leak, the gas escapes outside rather than into the living quarters. However, if a rock or debris were to rupture the line and a spark occurs, it could result in a catastrophic fire or explosion, causing damage to your vehicle and potentially harming you or those around you.

Additionally, there may be specific regulations regarding propane usage in certain areas, such as at gas stations, tunnels, or on ferries. These regulations often require turning off propane-powered devices as a safety precaution. Therefore, it is essential to be aware of and comply with any local laws and regulations regarding propane usage while driving to ensure a safe and legal journey.

It is generally unsafe to run a portable generator in a travel trailer or camper

• Safety Hazards: Portable generators can pose a safety risk if not properly secured and fastened. They may fall, move, or slide around, which could damage the generator or other components in the vehicle. In contrast, built-in generators are firmly fixed and secured, reducing this risk.
• Fumes and Carbon Monoxide Poisoning: Portable generators produce fumes and carbon monoxide (CO), a colorless and odorless gas that can be harmful or even deadly if inhaled. Proper ventilation is crucial to mitigate this risk. Built-in generators typically have exhaust systems that release fumes outside, away from the interior of the RV. When using a portable generator, it is essential to place it outside and away from the RV, with the exhaust pipe directed away from the vehicle. Additionally, having a functioning carbon monoxide detector in your RV is always recommended.
• Electrical Hazards: Using a portable generator in a moving RV introduces potential electrical hazards, especially if the generator is not properly covered or if underway connections are required. Built-in generators, on the other hand, have wiring and connection cords that are properly insulated, reducing this risk.
• Fire Hazards: Running a generator while refuelling or performing maintenance can pose a fire hazard. It is essential to turn off the generator before refuelling and to refrain from performing maintenance while the generator is running.
• Compliance with Laws and Campground Rules: In some states, it is illegal to have propane onboard a running RV or to run propane appliances or equipment at a gas station. Additionally, campgrounds often have defined hours for running generators to minimise noise and exhaust disturbances for other campers.
• Refuelling Concerns: Running a portable generator in an RV can impact refuelling stops, as it is generally unsafe to run the generator while refuelling the vehicle. This may require additional planning and coordination when travelling long distances.

While it may be tempting to use a portable generator to power your travel trailer or camper, prioritising safety and adhering to legal and campground requirements are of utmost importance. It is always recommended to consult with a professional RV expert to ensure any generator setup is secure and safe for operation.
