How to Choose Generators For Travel Trailer
Choosing a generator for your travel trailer is a significant decision that impacts your comfort, safety, and overall camping experience. Whether you are boondocking in a remote forest or tailgating at a stadium, the right generator provides the freedom to use your appliances wherever you go. However, the market is flooded with various types, sizes, and fuel options, which can make the selection process overwhelming for many RV owners.
Understanding Your Power Requirements
The first step in choosing the best generator for travel trailer use is determining exactly how much power you need. Generators are rated by “Starting Watts” (the surge needed to start a motor) and “Running Watts” (the continuous power provided). You should list all the appliances you plan to run simultaneously to find your total wattage requirement.
The Air Conditioner Factor
For most RVers, the air conditioner is the largest power consumer. A typical 13,500 BTU RV air conditioner requires about 2800-3000 starting watts and 1500-2000 running watts. If you plan to run your AC along with a microwave or hair dryer, you will likely need a generator in the 3500-watt to 4500-watt range. If you don’t use AC, a smaller 2000-watt unit may be sufficient for lights and electronics.
Sensitive Electronics and Clean Power
Modern travel trailers are full of sensitive electronics like TVs, laptops, and advanced control boards. Traditional “open-frame” portable generators often produce “dirty” power with high Total Harmonic Distortion (THD). You should look for an inverter generator, which produces a pure sine wave with less than 3% THD, ensuring your devices aren’t damaged by voltage fluctuations.
Portability and Handling
Since you will likely be moving the generator in and out of your tow vehicle or trailer storage, weight and size are critical factors. Most 2000-watt generators weigh under 50 pounds, making them easy for one person to carry. However, as wattage increases, so does the weight. Many 3500-watt to 4500-watt units now feature lightweight designs under 50 pounds, but larger units over 5000 watts will typically require wheels and a handle for mobility.
Fuel Types: Gasoline vs. Propane
Deciding between a single-fuel (gasoline) or dual-fuel generator is another vital consideration. Dual-fuel generators allow you to run on either gasoline or propane (LPG). Propane is often preferred by RVers because it burns cleaner, is easier to store without it going “bad,” and many trailers already have large propane tanks onboard for the stove and heater.
Benefits of Gasoline
Gasoline is more energy-dense than propane, meaning a generator will typically produce slightly more wattage when running on gas. It is also available at every gas station, making it easy to find while on the road. However, gasoline is highly flammable and can gum up a carburetor if left sitting for too long during the off-season.
Noise Levels and Campground Rules
Campgrounds often have strict rules regarding generator noise, usually requiring units to operate below 60-70 decibels. Inverter generators are significantly quieter than traditional models because they can throttle their engines down when demand is low. Look for units with an “Eco Mode” or “Economy Mode” to minimize noise and save fuel when you are only charging small devices.

Critical Safety Features
Safety should never be compromised when operating a generator near your sleeping quarters. There are two essential safety features every RV generator should have:
CO Shutdown Sensors
Carbon Monoxide (CO) is an odorless, colorless, and deadly gas. Many modern generators include a CO sensor (often branded as CO Shield or Watchdog) that automatically shuts the unit off if it detects dangerous levels of gas accumulating. This is a life-saving feature that is now standard on many top-rated models.
RV-Ready Outlets
Look for a generator that is “RV Ready,” meaning it has a built-in TT-30R (30-amp) or 14-50R (50-amp) outlet. This allows you to plug your trailer’s shore power cord directly into the generator without using dangerous or inefficient adapters. This ensures a secure connection and optimal power transfer.
Run Time and Fuel Efficiency
Finally, consider how long the generator can run on a single tank of fuel. A longer run time means you won’t have to wake up in the middle of the night to refuel. Most quality inverter generators will run for 8 to 10 hours on a 25% load, which is usually enough to get through a full night of sleep while running basic lights and fans.
Conclusion
Finding the right generators comes down to balancing your power needs with portability and noise constraints. By choosing an inverter model with a pure sine wave, a CO safety sensor, and an RV-ready outlet, you ensure your camping adventures are both comfortable and safe. Take the time to calculate your wattage needs before buying, and consider a dual-fuel model if you want the ultimate convenience of using the propane already attached to your rig.
