Has anyone thought about using LP as a backup if the NG stops flowing? I just ordered a Cummins RS36 generator that can run on both LP and NG. It will be setup on the NG coming into my home but I was thinking about putting a LP tank so we could switch over if the NG pumping stations have problems. LP can be stored for a very long time without issues. I think switching the Cummins from LP to NG is as simple as a change on the LCD control panel. Then have a valve to shut off NG and a valve to turn on LP. Would this be feasible?
