This is a much easier way to go than the earlier posted fixed Honeywell generator that is much more money. Granted 20 K is much more power too but this should run most homes at full home demand. Some electrical work will be needed to hook to your power panel and propane source. This is $400. less than the Duromax model also sold on Amazon. I paid no sales tax.
