I've never brought an electric skillet, but I'm sure it would be easily workable. I do bring the foreman grill or a microwave stack cooker. Depending on which I base my "cooking" on that.
The frige easily holds a gallon of milk, dozen water bottles, 12 pack of soda 4-6 beers, two wine bottles, half gallon of juice, dozen eggs, lunch meat, ygurt containers, cheese, mayo, frozen pancakes and frozen breakfast sausage, and 12 freeze pops! If I had wanted to get more creative I could have fit more!
My experience was that it was pretty small. You can fit necessities, and things for sandwiches and what-not, but not even a couple days worth of dinner groceries.
That little freezer section fits about two trays of ice cubes, we tried to fit frozen pops in there, but ended having to eat a few to make it work.
