It's a van. IMO, one of the compelling reasons for van camping is not having to use backpacking cook sets!
I have a 10" cast iron skillet and a cast iron lid to fit it - the lid is a Griswold, I don't know what brand the skillet is (no visible marks), but the iron is machined smooth like a Wagner or Griswold. (I estimate the skillet is a good 50 years old, it's an inheritance from my mother's second husband.)
I have several stainless steel saucepans with heavy bottoms, purchased singly from Ross Dress For Less. Which ones I take depends on my menus for the trip.
I have a stainless steel tea kettle.
I have a pressure cooker, but haven't taken it on a trip yet - so far, I just either cook beans at home, freeze them, and bring them, or use canned beans. But I am going to start experimenting soon with it on my coleman single burner.
