I have the same experience as Gypsy Wind, Generac 20-k, runs every thing on Ranch when Power out, my Dads house and mine are on end of line, we have gone as long as 12 days w/o power, they are LP. I bought both ours from Northern 12 years ago with switch for 4,300 a piece, with switch . Don’t know about the new ones, but have had great luck with ours, literally life savers, at 20 below and 18” of snow on ground.
