Our little 15A is all electric including a built in single "burner" induction cook top I installed. We love it. No CO, easy to clean, etc. But, just like all electric appliances, you will need to supply the proper voltage & current: Easy when connected to shore power but more complex & $$$ if you are not going to be connected to shore power (i.e., "boon docking/dry camping").
Although we consider ourselves "foodies", we don't like splatters and mess in our little trailer. So, for preparing anything seared, fried, etc., I use a compact single pan butane/propane burner for searing steaks, fish, etc., outside. We also have a portable single induction burner/element, but a vast majority of our camping is out in the middle of nowhere so the little butane/propane burner gets used when we need to cook something outside (conserves battery capacity).
