I too installed a 20kw generator from Koehler. We did it through generator connection and could not be happier. A 20kw takes a lot of prophane so make sure you get two tanks. Have it cycle every three weeks to save prophane. Get a prophane warmer also. The maintained plan is great. They come out once a year and change your oil and plugs and do all the yearly up grades. To me it was worth it.
