I know a lot of folks who are going to propane fired Genracs and such as a back up to the mains.. Sad to think that the power companies have let their lines get so bad that "Thousands without power" is a common occurrence. I grew up out in the boonies as it were (Story time: Went to buy propane, woman really wanted to give me directions to the tank farm.. She was sure I could not find it, Till I told her my name,,, It is the dairy farm I grew up on). I moved to the city I expected more reliable power.. Well on the farm, we occasionally lost power for a few hours, but I think one time we could not milk the cows with the power milker.
In the city,, Days without power is common.
This is why the first MOD I made to the motor home was so it could feed power to the house, which was also modified (Added proper generator transfer panel and inlet) so the motor home could feed it.
The box, wires, plugs, sockets and installation, Couple thousand dollars.
