I have a North Star 5500 watt generator that I really have no use for. This generator has maybe 5 hours of run time on it tops. I just never used it. Has 5500 watts max output and 4500 watts continuous power. 9hp Briggs Vangaurd engine. 120/240 volts. Comes with wheel kit already installed. Paid almost $1000, looking to sell for $600.
