Up for sale is a Champion 10,000 watt Tri-fuel Genset I recently paid $1400 for it and $150 for the AGM battery. Asking only $850.
It has less than 4 hours on the meter. I literally just filled it with synthetic oil and made a couple test runs, never needed to use it as backup power. I have it all hooked up and ready for you to see it running, you can even watch it power the entire house including the 3.5 ton AC unit
