Nice and not a bad price for a tri-fuel in this output range.
Does it have silly stuff like remote start?
My inlaws had a chinese ~5K watt inverter style unit with E-start and a FOB for remote start. You have to keep a battery tender on the E-start battery if you want to use it . For other built in electronics on it, their will be other small batteries on the unit somewhere. Those went completely dead on the inlaws in a year or so and the E-start battery not so long after that.
