Summary
The DuroStar DS13000MXT is a 10,500-watt tri-fuel generator built for high-demand applications. Its tri-fuel capability (gasoline, propane, natural gas) and 13,000-watt starting capacity make it suitable for whole-house backup, RV power, and job-site work where fuel supply flexibility matters.
The Ford FG5250PBR is a 4,250-watt dual-fuel generator that runs on gasoline or propane, delivering the power needed for household essentials during outages, RV camping trips, or job site work. Its 5,250 peak watts handle motor-driven appliances like refrigerators and well pumps without staggering loads. The 108-pound weight with included wheel kit makes it moveable but requires two people for comfortable transport.
