We have one, an off brand model from Amazon similar to this one https://smile.amazon.com/Euhomy-1500W-Comes-Recipes-Cookbook-Accessories/dp/B07B8PS6T3 in our coach, it works well, the only problem is portion size is limited (if overloaded it does not cook well), works great for one person, ok for two, but more than 2 people and you will run into its limitations. Mostly it is good for cooking frozen "fried" food style items with less grease, french fries, chicken strips, cheese sticks, corn dogs, etc., but is also good for corn on the cob and a few other things. Power draw is similar to running the microwave, cook times for most frozen items is around 12-15 minutes, though some stuff like corn on the cob takes 20 minutes or so. Certainly beats dealing with a hot oil fryer in an RV.
