Predator 9500 Inverter
Harbor Freight's giant-killer. The Predator 9500 delivers 7,600 running watts of closed-case inverter power — EU7000iS territory plus 2,000 extra watts — at 40% of Honda's price, and the r/Generator consensus is that the hardware genuinely delivers: clean power, 67 dBA that's dramatically quieter than open frames, electric start, ESC economy mode, and 18.5-hour runtimes. Owners run whole homes through the L14-30R and an interlock. The catch everyone leads with: a 90-day warranty from a company whose service model is 'bring it to the store,' so buyers treat the extended protection plan as mandatory. Other realities from long-term threads: 257 lbs makes it the heaviest thing in its class, it's carbureted (store it dry), CO Secure occasionally false-trips in enclosed-ish spaces, and there's no dual-fuel option at this size.
Specifications

Predator 3500 Inverter
The cult classic of the RV world. The Predator 3500 has powered a decade of forum threads titled 'why pay Honda prices?' — 3,000 running watts, 57 dB super-quiet operation, electric start, and a digital readout for around $800, with periodic coupons taking it lower. Owners report five-plus-year lifespans with basic oil changes, and it starts 15k BTU RV ACs that make 2,200W units give up. Consumer Reports rates it surprisingly highly for noise and power quality. The trade-offs are well-mapped: 99 lbs with no folding handle makes truck-bed loading awkward, the oil fill is tilted and messy, carb varnish after storage is the top repair thread, the 90-day warranty is the shortest in the industry, and CARB-state buyers need the newer CO Secure version. Still the value benchmark for RV inverters.
Champion's answer to the EU7000iS costs a third as much and adds propane capability: 7,000 running watts of closed-frame inverter power at a claimed 61 dBA from 23 feet, with both 50A and 30A 240V outlets ready for a transfer switch. Owners running whole-home essentials during outages report it handles well pumps, furnaces, and a smaller central AC, with quiet operation that genuinely surprises people used to open-frame roar. The CO Shield sensor and electric start round out a strong package. The complaint list from owner threads: at 214 pounds it's barely 'portable' despite never-flat wheels, the propane derate takes running power to about 6,300 watts, real-world noise climbs well above 61 dB under heavy load, and a few owners report early inverter-board failures — Champion support resolves them, but shipping a 200-lb unit for service is nobody's idea of fun.
The unicorn spec r/Generator kept asking for: tri-fuel AND inverter in one machine. Hook the 201176 to your natural-gas line for unlimited runtime, and unlike every conventional tri-fuel, it feeds your house clean sub-3% THD power that's safe for furnace boards, UPSs, and electronics — through a 50-amp outlet. On gasoline it makes 7,250 running watts; NG drops it to 5,875, still enough for most homes' essentials plus a small AC. It's an open-frame design, so the 72 dBA rating is real and load-dependent — quieter than a WGen9500DF, louder than closed-case inverters. Owner threads note the winning math (it replaced separate 'quiet' and 'NG' generators for many), with the familiar caveats: NG line pressure matters, the 420cc engine drinks on gasoline at full tilt, electric-start battery upkeep, and Champion's included NG/LP hoses are short. CO Shield included.
