I bought this Generator NEW from Costco and have not opened or used it. I bought two total, and the other one is running and is plenty sufficient for my needs. With a transfer switch, this model can run as a whole-home standby generator (auto on / off).

Not only can it run all the appliances in my home as a back up, it is mobile-friendly enough for long camping trips / RV alternative power source, or events or tailgating power. Firman is a highly reviewed brand, and I've operated my other T07571 for years and taken it all around the country with no maintenance so far.

Model T07571 - Tri-Fuel runs on Gasoline, Natural Gas, and Propane. 8 Gallon tank which will operate for 12 hours at 25% load.

Since this is brand new, unopened, it comes with a bottle of engine oil, oil funnel, spark plug wrench, and a double open-ended wrench (10mm/12mm), LPG regulator with hose holder, generator cover, and a power cord.

Has two wheels, and retractable lift handle.

This includes a 50-AMP 120/240V outlet (14-50r), a 30-AMP 120/240V twist-lock outlet (L14-30R), a 30-AMP 120V twist-lock outlet (L5-30R), and two GFCI 20A 120 household duplex outlets (5-20r).
