Propane RV Generators
Propane RV Generators for Fuel That Doesn't Go Bad
Propane's biggest advantage for RV owners is shelf stability, since a tank can sit unused between trips for months without the fuel degrading the way gasoline does. This propane RV generator collection spans DuroMax's dual and tri fuel lineup, Cummins Onan's dedicated RV propane units, and dual fuel inverter models, giving RV owners propane-capable options across a wide range of output.
Cummins Onan: Propane-Specific RV Models
The Cummins Onan 2500 Watt and 3600 Watt propane RV generators are built specifically around propane operation, CARB-compliant for travel through California and designed for onboard RV integration. These sit alongside the QG 7000i DF and dual fuel inverter models like the P4500iDF, P5000iDF, and P9500DF, which run on propane as one of two fuel options rather than propane exclusively.
DuroMax: The Widest Range for Propane Flexibility
DuroMax dominates this collection by sheer range, from the 5,500 Watt Dual Fuel HX up through the XP28000IHT at 28,000 watts. For RV use specifically, the inverter tri fuel models, the XP7000iHT, XP11000iHT, and XP16000iHT, add natural gas as a third fuel option beyond gas and propane, worth considering if you have access to natural gas at a home base between trips, though propane remains the more universally available option while traveling.
Frequently Asked Questions
Why do RV owners specifically favor propane over gasoline for backup power?
Propane doesn't degrade in storage the way gasoline does, which matters for RVs that might sit unused for weeks or months between trips, since a stored gasoline supply can go stale and cause starting issues, while propane remains usable indefinitely as long as the tank stays in good condition. This makes propane a more reliable choice for a generator that isn't run constantly.
Should I choose a dedicated Cummins Onan propane RV unit or a DuroMax dual fuel model?
The Cummins Onan propane RV generators are purpose-built for onboard RV mounting and integration, while DuroMax's dual fuel units are portable generators that happen to work well for RV use, offering the flexibility to also use them at home or a job site between trips. If you want a fixed, dedicated onboard solution, Cummins Onan fits that role; if you want dual-purpose flexibility, DuroMax is the better fit.
Is it worth paying more for a tri fuel model if I mainly plan to run on propane?
If you don't have regular access to natural gas at a home base or elsewhere in your travels, the added natural gas option on a tri fuel unit doesn't add much practical value beyond what a standard dual fuel model already provides, since you'd primarily be using gasoline and propane anyway. In that case, a dual fuel unit like the XP13000HX or DS13000MX is generally the more cost-effective choice.
