Yes.
In 2003 we had bought a Honda 3000 when we were ready to move, as we knew we would be living in the camper for awhile. We also didn’t know how often the electric might go out once we got in the house.
It got used every evening for a few hours, for two months, waiting on the house. After that it has only been a handful of times during storms, but well worth it if the power goes out more than an hour.
The year of the BIG ice storm, power kept going out because trees were snapping left and right. It sounded like a literal war zone up on the ridge. The total hours of lost power that week were 108 hours — I kept track.
So yes that 22 year old generator has more than paid for itself.
