The Generac 12,500W Tri-Fuel Portable Generator delivers unmatched flexibility with the ability to run on gasoline, liquid propane, or natural gas—making it ideal for RV owners who want reliable backup power without being tied to one fuel source.

This generator stands out because it combines high output with practical fuel options, letting you switch between fuels based on availability and cost. The automatic shut-off for CO detection adds peace of mind, especially when parked in enclosed spaces like garages or RV pads. Plus, its quiet operation means you won’t disturb neighbors during tailgates or overnight stops.
