Excellent idea I did the same about 2 years ago after having to toss out $300 dollars worth of food twice in one year.
Since then I have used it on two occasions and I can it set up in under 5 min.
Just make sure you have sufficient gas on hand because if it is a major outage there will not be a gas station in your area with the ability to pump.
I have a 15 gal hand cart that I use to refill my boat, it would run my generator for well over a week.
I’ve got a boat too and always have non-ethanol gas on hand for it. Gonna have to buy a couple more 5 gallon containers though:-)
