100KW Generator

I believe it's a kohler, helping my father in law sell it. 100kw generator with a john deere engine. Has about 250hrs on it. Was a back up generator for a robotic dairy in Idaho. In decent shape. Does come with the fuel tank base. It is in south eastern idaho. Asking 20k. If you want I can deliver it up here and to surrounding areas for a fee about 5 or 6 days after the new year. You just need to be able to unload it off the trailer. Thanks!
