Understand. Going full bore on a problem that only happens once every few years is not financially provident.
I see a few propane (dual fuel) generators on Facebook Marketplace I think might be just the ticket.
My brother, the mechanic, laughs at me for how many gas-powered things I’ve ruined over the years—garden tractors, tillers, lawnmowers, chainsaws, weed whackers...
My research show propane won’t have this kind of old fuel problem, and yes I do use gas stabilizer.
Agreed, not much sense in wiring for a whole house support if it only occurs a few hours per 20-30 years.
The small gens also have a use in that you can place them in a wheelbarrow and take them out on the acreage for power to do stuff.
'course, with the now battery powered everything, not so much.
I own a duel duel generator and love it. All I use is propane in it. Will never go back to gas.
I bought one that produces 3500 KW for $500 bucks and hooked up everything in my house which took a little over 1000 watts.
