I'm not the cook so I don't recall if my wife brought a Crock Pot along or not, but I do carry a heavy extension cord and a folding table. For things like the electric skillet we set it up outside. Most campground power posts will also have a regular 110 volt 15 or 20 amp outlet too. So I normally plug directly into that and the wife has done the cooking outside. My BIL and SIL and their kids often come with us with their TT and he had problems with plugged in electrical cooking devices pooping circuits inside the TT so he now does the same.
