If I ever install a back up generator, I'd run it on propane. Pump gas is obviously a PIA with constant refills and post event gouging / shortages. Natural gas isn't an option here and no guarantee it would be available after a storm anyway. A 500 lb propane can somewhere high and dry should run it for at least a week and never been in the dark more than 3 days. Over sized solar / battery setup will likely happen before a generator.
Absolutely. A small power plant I worked at had a Waukesha 6 cylinder gasoline emergency generator. Never reliably started. Converted it to natural gas and the no-start problems went away. Propane would offer the same reliability.
