Get the Most Out of Your RV Generator: Best Practices for Campers

The open road, breathtaking vistas, and the freedom to explore wherever your wheels can take you – that’s the allure of RVing. But sometimes, the perfect campsite isn’t hooked up to shore power. That’s where your RV generator becomes your best friend, providing the electricity needed to run your lights, appliances, and crucial comforts like air conditioning or heat.

However, an RV generator is more than just a power source; it’s a complex piece of equipment that requires care and understanding to perform reliably when you need it most. Getting the "most" out of your generator isn’t just about powering your devices; it’s about ensuring its longevity, efficiency, safe operation, and being a good neighbor.

This article dives into the best practices for RVers to maximize the performance, lifespan, and reliability of their onboard or portable generators.

Understanding Your Powerhouse

Before you can get the most out of your generator, you need to know its basics.

• Type: Is it a built-in generator (often fueled by your RV’s main fuel tank or propane) or a portable unit (gasoline or propane)? Built-in generators are convenient but require more specialized maintenance access. Portable units offer flexibility but require setup and fuel management.
• Fuel: Most RV generators run on gasoline, drawing from the vehicle’s tank (usually only down to about a quarter tank to prevent you from being stranded). Some run on propane, and a few are diesel. Knowing your fuel type is fundamental.
• Wattage: Every generator has a running wattage (what it can sustain) and a surge wattage (a brief burst for starting motors like AC units). Understand your generator’s capacity and the power requirements of your appliances. Overloading is a sure way to damage the unit.
• Manual: The single most important resource is your owner’s manual. It contains specific maintenance schedules, troubleshooting tips, and operational details for your specific model. Keep it handy!

The Cornerstone of Reliability: Regular Maintenance

Just like your RV’s engine, your generator is a small engine that needs TLC. Neglecting maintenance is the primary reason for generator failure.

1. Check Oil Levels Regularly: Before each use, check the oil level. Low oil can cause catastrophic engine damage. Use the type and weight of oil recommended in your manual.
2. Change the Oil and Filter (if applicable): Follow the service interval in your manual, typically based on operating hours (e.g., every 100-200 hours after the initial break-in period). This is non-negotiable for longevity. Use fresh, clean oil.
3. Inspect and Clean/Replace Air Filters: A clogged air filter starves the engine of air, reducing performance and potentially causing damage. Check it frequently, especially if operating in dusty environments. Clean or replace as needed per your manual.
4. Check and Replace Spark Plugs: A fouled or worn spark plug can cause misfires, hard starting, and poor fuel efficiency. Inspect it periodically and replace it according to the recommended schedule.
5. Maintain the Fuel System: This is often the most problematic area, especially with modern gasoline containing ethanol.

   • Use Fresh Fuel: Stale fuel can gum up the carburetor or fuel injection system. Don’t let fuel sit in the tank for months.
   • Use Fuel Stabilizer: If you won’t be using the generator for more than a few weeks, add a quality fuel stabilizer to the tank and run the generator for a few minutes to ensure the treated fuel circulates throughout the system.
   • Exercise the Generator: This is crucial! Even if you’re plugged into shore power, start and run your generator under a moderate load (like running the AC) for 30-60 minutes at least once a month. This keeps internal components lubricated, circulates fuel, and helps prevent fuel system issues.
   • Consider Draining the Carburetor: For long-term storage, some manuals recommend draining the carburetor bowl to prevent fuel evaporation and gumming. Consult your manual.

Operational Best Practices

Proper operation goes beyond just pressing the start button.

1. Pre-Check: Before starting, ensure the generator has adequate fuel and oil, and that the exhaust is clear and pointed away from people, pets, and the RV.
2. Starting: Follow the specific starting procedure in your manual (choke, prime, etc.). Don’t just grind the starter repeatedly if it doesn’t catch.
3. Warm-Up: Allow the generator to run for a few minutes before applying a load. This lets the engine reach operating temperature and the oil circulate properly.
4. Apply Load Gradually: When turning on appliances, start with the largest load first (like the AC), then turn on others. This prevents excessive surge demands simultaneously.
5. Monitor Load: Be mindful of the total power you’re drawing. Avoid running all high-draw appliances (AC, microwave, coffee maker, hair dryer) at the same time if your generator can’t handle it. Use an energy management system or simply be conscious of what’s on.
6. Cool-Down: Before shutting down, turn off all connected appliances and let the generator run for a few minutes with no load. This allows it to cool down gradually, which is better for its internal components.
7. Proper Shut-Down: Follow the shut-down procedure in your manual. For built-in generators, this is usually a simple switch. For portables, there might be a fuel shut-off valve to run the carburetor dry (if recommended).

Safety Above All Else

Generators produce carbon monoxide (CO), a colorless, odorless, deadly gas. Safety is paramount.

1. Install and Test CO Detectors: This is non-negotiable. Have working carbon monoxide detectors inside your RV and test them regularly.
2. Vent Exhaust Properly: Ensure the generator’s exhaust is always directed away from the RV, neighboring campsites, windows, doors, and vents. Wind can carry exhaust fumes unexpectedly.
3. Never Operate Inside: Never run a generator inside the RV, in a basement compartment (unless specifically designed with external venting and the door is open/vented), or in any enclosed space.
4. Maintain Clearance: Keep adequate clearance around the generator for ventilation and cooling, as specified in your manual. Keep flammable materials away.
5. Electrical Safety: Ensure all electrical connections are secure and rated for outdoor use if applicable. Never operate in standing water or wet conditions without proper protection.

Being a Good Neighbor: Noise and Etiquette

Generator noise can be disruptive in quiet campgrounds or natural settings.

1. Know Campground Rules: Many campgrounds, especially public ones (National/State Parks), have strict "quiet hours" during which generator use is prohibited. Respect these rules.
2. Location, Location: If using a portable generator, place it as far away from your neighbors as practical, while still maintaining safety clearances and directing exhaust appropriately.
3. Consider Noise Levels: Inverter generators are significantly quieter than conventional open-frame generators. If noise is a major concern and you’re in the market for a new unit, an inverter model is often worth the extra cost. Built-in RV generators often have sound-dampening enclosures.
4. Limit Run Time: Only run the generator when necessary to recharge batteries or power high-draw appliances. Avoid running it unnecessarily for long periods.

Handling Environmental Factors

Generators can be affected by conditions.

1. Altitude: At high altitudes, engines lose power due to thinner air. Your generator’s effective wattage will be reduced. Consult your manual or a dealer about high-altitude kits or adjustments if you frequently camp at elevation.
2. Temperature: Extreme heat can cause overheating. Ensure adequate ventilation. Extreme cold can make starting difficult; use proper starting procedures and potentially a cold-weather kit if available.

Long-Term Storage

If you won’t be using your generator for an extended period (e.g., winter storage), proper preparation is key to ensuring it starts easily next season.

• Add Fuel Stabilizer: As mentioned, add stabilizer to the fuel tank and run the generator to circulate it.
• Change Oil and Filter: Store the generator with fresh oil. Used oil can contain contaminants that can cause corrosion over time.
• Address the Fuel System: Depending on the manual, this might involve draining the carburetor or the entire fuel tank if storing for many months.
• Clean: Give the generator a good cleaning to remove dirt and debris.
• Storage Location: Store in a dry, protected area.

Conclusion

Your RV generator is a key component that unlocks greater freedom and comfort in your camping adventures. It allows you to venture beyond the confines of full hookups and enjoy the solitude and beauty of off-grid locations. However, this freedom comes with responsibility.

By understanding your generator’s capabilities, adhering to a consistent maintenance schedule, practicing safe operation, being mindful of noise, and preparing it properly for storage, you ensure it remains a reliable source of power for years to come. Don’t wait until you’re miles from anywhere and the generator won’t start to think about its care. Implement these best practices now, and you’ll truly get the most out of your RV generator, powering countless memorable camping experiences. Consult your owner’s manual religiously – it’s the definitive guide to keeping your specific unit running smoothly.

Q2: What kind of fuel should I use in my generator?
A2: Most RV generators use unleaded gasoline. Always use fresh fuel and check your manual for the recommended octane rating. Some larger or older units may use diesel or propane.

Q3: Can I run my generator all night?
A3: While generators are built to run for extended periods, consider noise rules (many campgrounds have quiet hours), fuel capacity, and most importantly, safety. Ensure proper ventilation and that your CO detector is working. Running continuously might not be necessary if you primarily need power for battery charging or brief appliance use.

Q4: My generator won’t start. What should I check?
A4: Common culprits include: low fuel, low oil (many have safety shut-offs), stale fuel, clogged fuel filter or carburetor, dirty spark plug, or issues with the choke/prime procedure. Consult your manual’s troubleshooting section.

Q5: How much power (wattage) do I need from my generator?
A5: This depends entirely on what you want to power. Add up the running wattage of the appliances you might use simultaneously. Pay special attention to high-draw items like air conditioners, microwaves, and electric heaters. Your manual will list your generator’s running and surge wattage.

Q6: Do I really need a carbon monoxide (CO) detector?
A6: ABSOLUTELY YES. Carbon monoxide is deadly and odorless. Generators produce CO. A working CO detector is essential safety equipment whenever you are using a generator near or in your RV. Test it regularly.

Q7: Is it okay to run my generator in the rain?
A7: Portable generators should ideally be operated under some form of cover that still allows ample ventilation to protect them from moisture without trapping exhaust. Built-in generators have weatherproof enclosures but ensure exhaust ports remain clear. Never operate any generator standing in water.

Q8: How often should I "exercise" my generator?
A8: Run your generator under a moderate load (at least 50% capacity, like running the AC) for 30-60 minutes at least once a month. This keeps it healthy, lubricates seals, and circulates fuel, preventing carburetor issues.

Q9: Does altitude affect generator performance?
A9: Yes, engines lose power at higher altitudes due to thinner air. A generator rated for 3000 watts at sea level might only produce 2500 watts or less at 5,000 feet. High-altitude kits are available for some models to help compensate.

Q10: What’s the difference between a conventional and an inverter generator?
A10: Conventional generators run at a fixed engine speed (usually 3600 RPM) and produce power directly. Inverter generators run at variable speeds depending on the load, produce AC power, convert it to DC, and then "invert" it back to clean AC power. Inverter generators are typically much quieter, more fuel-efficient at lower loads, and produce "cleaner" power suitable for sensitive electronics.
