Overview of Each Generator
6800W Dual-Fuel 120V/240V Inverter Generator: This model delivers up to 6,800 peak watts on gasoline and 6,100 on propane, with 5,000/4,500 running watts respectively. It offers both 120V and 240V output, electric and remote starting, and is described as suitable for RV camping, selected home backup, workshops, and outdoor power.

The brand markets it as RV-ready for camping and essential home backup without moving to a larger generator.
Where They Differ
The most significant differences are in power output, fuel type, voltage, weight, and noise. The 6800W model produces 70% more peak watts on gas (6,800 vs 4,000) and supports propane, while the 4000W model is gas-only. Voltage coverage differs: 120V/240V vs 120V only. The 4000W model is quieter (60.5 dB vs not stated) and lighter (65 lb vs not stated), making it more portable. Starting method is electric/remote on the 6800W; the 4000W’s starting method is not stated by the brand.
Which Fits Which Need (by Criteria)
Power needs: If you need to run a large RV air conditioner, well pump, or 240V tools, the 6800W dual-fuel is the clear choice. For smaller 120V devices like a refrigerator, lights, and a small AC, the 4000W will suffice.
Fuel preference: The 6800W offers propane as an alternative to gasoline — useful for long outages or cleaner storage. The 4000W is gasoline only.
Portability and noise: The 4000W wins on weight and known noise level (65 lb, 60.5 dB). The 6800W does not have these specs stated, so it may be heavier and louder.
