Nobody told me not to, didn't mean to infer you can't, My point was why? My elec heats up in less than 5 min, 2 min on propane. When setting up at the site, the water is usually up to temp before you need it anyway. If you leave both on, the odds of forgetting one or the other when breaking camp are greater which increases your risk to boil your tank dry and wastes propane when off power. Also never run into issue of running out of hot water either just using elec or propane alone.
My advice is one or the other to keep things simple and save on propane when you have elec available.
