I can see that the biggest advantage might be the heating up the interior of the camper...But I think if you are a "serious" Cook these just are not going to work that well.
When I do a pan roasted Chicken breast (or anything else) I start it on the stove top then move it to the oven to finish. Then I plate it to rest and start the sauce... I will normally add Brandy, Bourbon or Sake to deglaze the pan and flame it. This gives the sauce that glossy look and reduces it faster. This is a technique you lose completely with induction as tipping the pan to expose the alcohol to the flame heat cant happen.
And there are times and recipes that call for certain types of pans. Not all of which will work with induction.
I think I will stick with my propane and the campfire and my Gas Grill.
