Yep twice.
Once at a NH campground after the electric went out in the early evening (We think a car hit a pole down the road). Owners were gone and there were just a couple of campers in the CG. The campground generator didn't start. Electric and water were up and running in the morning.
Second time was a hurricane (AND I got an atta-boy for traveling with a full tank of fresh water!) We were in a campground in ME during the hurricane. All power was lost on Monday including the water pumps when some trees took out the electric in several places both at the CG and the town (no backup generator).
Water and electric weren't available until Thursday afternoon. BUT because I was smart enough to bring 40 gallons of water, we could sponge bath and have drinking/cooking water for the week.
The battery would last during the night so I'd hook up the truck and let it idle for a couple of hours during the day to charge the battery. Fun time...
