For us the decision was based on the camping we've done. We often camp without power, but want to be able to run the A/C (and microwave). So as a result we're already running with generators. When we cook without power or sometimes just for preference we typically use the grill...we are often at social gatherings and prefer to cook out with friends.
Hubby also wasn't wild about the heat the gas burners gave off. Those upper cabinets stay a lot cooler since we made the change.
We do still keep the propane for the
fridge. We don't run the generators full time.
