Dual Fuel Diesel Generators: How the Top Picks Compare

Which model offers the most runtime on gasoline?

The Westinghouse iGen5000DFc leads with up to 18 hours of runtime on its 3.4-gallon gas tank, thanks to Economy Mode. The iGen4000DFc runs up to 7 hours on a 1.69-gallon tank, while the maXpeedingrods MXR4000GT does not specify a runtime figure but operates on a dual-fuel system with similar tank capacity. For extended use, the iGen5000DFc is the clear winner.

How do their power outputs compare for RV use?

The iGen5000DFc delivers 5000 peak watts and 3900 rated watts, making it the most powerful of the three. The iGen4000DFc and MXR4000GT both offer 4000 peak watts, but the MXR4000GT drops to 3600 peak watts on propane. All three include an RV-ready outlet, but the iGen5000DFc can handle larger loads like a 30-amp RV air conditioner more comfortably. If you need more power for a travel trailer, also see our best RV generators dual fuel recommendations.

Which generator is the quietest?

Both Westinghouse models operate at as low as 52 dBA, which is whisper-quiet for a generator. The maXpeedingrods MXR4000GT is rated at 58-60 dBA in Eco mode, slightly louder but still very quiet for camping. For reference, 52 dBA is about the level of a quiet conversation, while 60 dBA is closer to normal speech. The Westinghouse units have the edge in noise reduction.

What about smart features and starting options?

The maXpeedingrods MXR4000GT stands out with Bluetooth app remote start, letting you start and stop the generator from your phone. All three models offer remote start key fobs and electric start, plus recoil backup. The Westinghouse units include a digital LED display showing fuel level, power output, and remaining runtime.

Buying Guide for 2026

Dual fuel flexibility: gas vs. propane

All three generators run on both gasoline and propane, but propane produces slightly less power. For example, the maXpeedingrods MXR4000GT delivers 4000 peak watts on gas but only 3600 on propane. Propane is cleaner and stores indefinitely, while gasoline offers higher output and longer runtime per tank. Consider your fuel availability and storage preferences.

Inverter technology and clean power

All three models are inverter generators with less than 3% total harmonic distortion (THD), making them safe for sensitive electronics like laptops, phones, and RV appliances. This clean power is a key advantage over conventional generators for anyone powering modern devices.

Warranty and support

Westinghouse backs both the iGen4000DFc and iGen5000DFc with a 3-year limited service, labor, and parts warranty. maXpeedingrods offers a 2-year warranty. A longer warranty often indicates higher confidence in build quality, which is worth considering for a long-term investment.

Frequently Asked Questions

Can these generators run an RV air conditioner?

Yes, all three models have an RV-ready outlet and sufficient starting watts for most 13,500 BTU RV air conditioners. The Westinghouse iGen5000DFc is best suited for larger units or running additional appliances simultaneously.

How do I start these generators remotely?

The Westinghouse models include a key fob for remote start, while the maXpeedingrods MXR4000GT adds Bluetooth app control via your smartphone. All three also offer electric start and a recoil backup.

Are these generators quiet enough for camping?

Yes. The Westinghouse units operate at as low as 52 dBA, and the maXpeedingrods at 58-60 dBA in Eco mode. These noise levels are comparable to a quiet conversation and are generally acceptable at campgrounds. For quieter options, check our best RV quiet generators guide.

What is the difference between peak and rated watts?

Peak (or starting) watts are the surge power needed to start motors and compressors, while rated (running) watts are the continuous power the generator can supply. For example, the iGen5000DFc has 5000 peak and 3900 rated watts. Always ensure your total running load stays below the rated wattage.
