Shopping for a dual fuel RV generator means balancing three things at once: how much power your rig really draws, how quiet the unit needs to be for campground rules, and whether gasoline or propane will be easier to find on your trips. This list compares six well-known options with those criteria in mind. Each pick is selected from manufacturer specifications, brand reputation and common owner feedback patterns. We have not run any of these units ourselves, so treat the specs as the manufacturer states them and check current details before you buy.

- Dual fuel operation on gasoline or propane
- Electric start
- Conventional engine design
Pros
- Strong surge capacity helps with motor-driven appliances

Honda EU2200i Companion (dual fuel-compatible models)
Honda’s EU2200i line is best known for quiet, low-emission operation, and some owners pair compatible setups to run on propane when gasoline is hard to find. It fits small RVs, pop-ups and van builds where noise rules are strict and the electrical load stays modest.
Key specs
- Rated running output in the 2,200-watt class
- Inverter design with variable engine speed
- Very low noise output for its power class, per manufacturer specifications
- Compact, lightweight frame
Pros
- Among the quieter options in its class, which suits strict campground rules
- Compact and easy to carry
- Strong reputation for reliability and service
Cons
- Output is too low for air conditioners or most high-draw appliances

Buying Guide
Choosing a dual fuel RV generator is mostly a matter of matching output, noise and fuel behavior to how you camp. The sections below walk through what to compare. For background on noise terms, see Generator Decibel Ratings Explained: What dBA Numbers Mean and How to Compare Generator Noise Ratings Fairly.
Selection criteria
- Running watts: Add up what you plan to run at the same time, then add a margin.
- Noise: Check the rated dBA at a stated distance. Compare numbers measured the same way.
- Fuel flexibility: Confirm which fuels the unit supports and what its output is on each.
- Portability: Weight and frame design determine whether one person can move it safely.
Important features
Inverter generators vary engine speed to match load, which usually makes them quieter and more fuel-efficient at partial loads. Conventional generators run at a fixed speed and tend to be louder, but they are often more affordable per watt and handle large motor surges well. Electric start is a practical convenience, especially in cold weather. Check whether the unit includes an automatic low-oil shutdown, which protects the engine.
Specs to check
- Rated running watts on gasoline and on propane (they are usually different)
- Starting or surge watts, which matter for air conditioners and refrigerator compressors
- Rated dBA and the distance it was measured at
- Fuel tank size and runtime at 50 percent load
- Outlet types (120V, 30-amp RV outlet, or both)
Choosing by need
- Quiet camping and electronics only: An inverter model in the 2,000 to 3,500-watt class is usually the best fit.
- Air conditioning or heavier loads: A larger conventional unit with strong surge capacity is more realistic.
- Mixed use with frequent moves: A lighter inverter with a dual fuel switch simplifies setup.
Things to watch out for
Propane rated output is almost always lower than gasoline output, so don’t assume the gasoline number applies to both fuels. Carbon monoxide is a serious hazard. Never run a generator inside an RV, tent, garage or enclosed space, and keep it well away from openings. For placement and exhaust safety, see Where to Place a Generator for Less Noise and Safe Exhaust. If you are unsure about wiring the unit to your RV’s electrical system, consult a qualified RV technician or electrician.
Maintenance also affects noise and reliability over time. Clean air filters and fresh oil keep a generator running smoothly, as covered in Generator Maintenance Basics: Oil, Air Filter, Spark Plug and Fuel.
FAQ
Can a dual fuel RV generator run on both gasoline and propane?
Yes. Dual fuel models are designed to run on either fuel, usually with a switch or valve. Output is typically lower on propane, so check the rated watts for each fuel in the manufacturer’s specifications.
Is propane or gasoline better for an RV generator?
Propane stores well for long periods and is often easier to source at campgrounds, while gasoline usually gives higher rated output. The better choice depends on your trip length, fuel availability and load.
How many watts do I need to run an RV air conditioner?
Small rooftop units often need starting surges well above their running watts. Check the air conditioner’s starting and running requirements and choose a generator with enough surge capacity. Smaller inverter models usually cannot run central or large rooftop units.
Are inverter dual fuel generators quieter than conventional ones?
Generally, yes. Inverter designs adjust engine speed to load, which tends to lower noise at partial loads. Compare dBA ratings measured at the same distance, since noise figures are not comparable otherwise.
Can I convert a gasoline generator to propane?
Some models offer conversion kits, while others are sold as dual fuel from the factory. Only use a conversion that the manufacturer approves for your model, and have it installed according to the instructions. If you are unsure, consult a qualified technician.
Where can I safely run a dual fuel generator at a campsite?
Run it outdoors, on level ground, at least several feet from the RV and any openings, with the exhaust pointed away from people and structures. Never run it inside a vehicle or enclosed area. Check campground rules on quiet hours before you start.
How long will the fuel last?
Runtime depends on tank size, fuel type and load. Manufacturers usually publish runtime at 25 or 50 percent load. Use that figure as a rough guide and check your actual usage.
Conclusion
For quiet overnight camping with electronics and modest appliances, an inverter dual fuel unit such as the Champion 3500-watt model or the Westinghouse iGen4500DF is a sensible starting point. If you need more running capacity and don’t mind more noise, the Champion 4000-watt, Generac GP3300DF or DuroMax XP4850EH cover larger loads. For very small rigs with strict noise limits, a compact Honda EU2200i-class unit is worth a look, though you should confirm dual fuel compatibility first. Match the watts to your real load, read the propane ratings separately, and check campground quiet-hour rules before you buy.
