If Generac has long lead time.. I went with 20kw propane Cummins air-cooled installed by authorized dealer in Royston, around $9K, the genset auto-runs for 15 minutes twice a month, very happy so far, BIG peace of mind
I’ve only had 1 power outage since last November, was running 4 hours or so in middle of night, never woke me up although genset is 35 feet from my bed.
I changed from the Generac unit to the Cummins. The delivery date for the Generac would have been Dec or Jan.
